  • wow i learned more from this than from my teacher all year . when your adding multiple elements together, like say you have oxygen, sulfur and cholide , how would you do that?

  • At the last few seconds you gave some practice questions so where do we find the answers

  • Thank you so much! Your'e better than my teacher!

  • I HAVE A POOPY BUTT AND I NEED TOILET PAPER!!!!!!!

  • ITS NOT TRUE. ITS FAAAAAAAAAAAAAAAAAAAAKE

  • thank you so much i hav exams in a couple day and i wouldve been screwed if not for this

  • I am self teaching myself chemistry from when i was at school as I did not pay attention and have no gcse's etc. I am 31 now and wish I would have paid more attention. You make it so easy by the way you explain things that if my teachers explained things that way I might have understood and wanted to learn. Teachers should have to watch your videos as part of their training!!!

  • this guy needs to be my teacher! all my teacher does is sleep in class. I have exams tomorow and ive learned more from google in 3 hours than i have from her all semester long, no joke.

  • how can you tell if a formula is not reactant? for example  NH4 +1 + PO4 -2 <little two btw not minus

  • so how do you simplify an element like i dont know umm . . . . phosporus dioxide or PO(subscript 4) which has a negative 3 charge and aluminum with a plus 3 charge ?

  • Man Your videos are so great and clear......oh and I also subscribed so I can watch our new videos!

  • whats the difference between ATE and ITE? I still dont get that

  • @tanho12 if its a polyatomic or a ternary the ending would be ate and if its binary than it would be ide!

  • what steps do you follow when you have two metals?

  • I almost forgot to ask, How do you know where to put all the dots during the configuration of how the ionic bond forms? does two dots go on one side? It may seem like a stupid question, i am slow at times, but it confuses me.

  • @lamya1961 you have to know your oxidation numbers from your periodic table from the metal and non metal side

  • Why can't you be my teacher instead of the friggin' retarded lady i have now? You make things SO much easier to understand! <3

  • Thank you so much for your helpful videos. Please be my chemistry teacher!

  • this guy needs to teach my chem class.

  • OMG Thank you it final makes sense

  • Thanks so much!I have always cruised through school because i am actually pretty smart (not to boast or anything). But im now in 8th grade and all my other classes that are honors courses i am doing really well, like A+ well, but my science techer hates everybody and hates it when you ask questions and then frowns upon you, so no one asks any.I have test tomorrow but i am usually consumed in music hence the nameGreenDayGuitarist, so this helped alot because my teacher also cant explain for shit

  • Comment removed

  • life saver! thank you so much!

  • Thank ypu SO much!! My teacher cant teach anything and you explained it perfectly :)

  • maybe one day youtube will reach every single class cause teachers cant teach

  • It's sad whenyou have to get on YouTube to learn something that your teacher cantteach you. Anyways THANK YOU VERY MUCH!!

  • @773aztec so true-teachers nowadays are mean,snotty, and suck t their job-some not all! others can be nice

  • Thank you, this was very helpful! I just wish I would have taken my test on binary compounds after I watched this video..

  • SDFJLSDLGJ thankyou so much

    please be my teacher:(

  • To find the charges of each atom using the P. Table, you just do this: period 1 has a charge of +1, p. 2 has a charge of +2, and p. 13 has a charge of +3. For period 15, it has -3, 16 has -2, and 17 has -1. Hope this helps, and I'm srry if I made a mistake!

  • Thank you so much! This was so helpful. I feel like I understand this now. Great video!!!!!!

  • How do we use the periodic table to find the charges of each atom?

  • @0MGARSH Yeah, I have the same question.

  • @0MGARSH For instance, those elements belonging to group 1A have only one valence electron and their charge is +1.

    group 2A- 2 valence electrons, charge is +2.

    group 3A - 3 valence electrons, charge is +3.

    group 4A - 4 valence electrons, charge can be +2 or +4. It depends.

    group 5A - 5 valence electrons, charge is -3.

    group 6A - 6 valence electrons, charge is -2.

    group 7A - 7 valence electrons, charge is -1.

    group 8A - 8 valence electrons, complete octet

  • @alcarfre thank you!

  • you make it so much easier to learn! thank-you! and ur not boring doing it!

  • Excellent! You saved me for my quiz tomorrow!

  • THANK YOU!!!!

  • The reason I'm spending the effort to write such a message is because of the frustration I encountered and experienced over the past few days. However, once seeing your videos, I now have a much clearer understanding, and that makes me very very happy.

    So once again, I want to thank you very very much for your excellent tuition through your videos, and I hope you keep doing these.

    Have an excellent week!!!

  • However, you come in. A excellent teacher must be able to both have knowledge and the skill to share it. You sir, can do both in a magnificent manner. If you are a teacher, your students are some very lucky people. If you are not, your knowledge and skill puts many teachers I know to shame, and I would gladly trade some of them for you.

  • Bless you so much.

    I started my high school unit in Chemistry, and it is my goal to do well in it, since I'm taking Honours Science.

    My teacher is very knowledgeable and his information is very accurate. I believe he also has a degree in Science, though I do not know what kind. Unfortunately it doesn't do squat when it comes to teaching. He has the knowledge, but can't even teach us it in a logical, systematic manner. He usually instead rambles, jumps back and forth, and goes very fast.

  • thks a lot, i have a unit test tomorrow on chemistry, and this was the only thing that was bugging me... really helpful video

  • wait when you said, "from the periodic table we'll notice that sodium has a +1 charge and chloride has a -1 charge" how do you know from the periodic table that an element is negative or postively charged?

  • Hey thanks

    My teacher sucks she doesnt teach and makes us just take notes

    It sucks no one learn anything in that class

  • Wow this is so helpful I have a test tomorrow so thanks a lot! :-)

  • i don't understand how to get the charges! i need help on that! do you have a video on that?

  • THANK YOU SOOO MUCH!! this is really helpful.

  • People this stuff is simple and this guy is a great teacher

  • how do you know what to write for the superscripts?

  • @supplytheginger You need to know the charges of each atom. Use the periodic table I have provided on this video.

  • this guy is amazing. i learned more in this 10min then in my 3 hour lab class! awesome job

  • This guy is just awesome. I actually learned something.

  • What if they already have numbers e.g Ca2+ and CO3 2- ?? help please

  • @WarTornSoilder the ions will always have the same number for example a soidum will always be 1+...

    so when u have Ca2+ and co3+ you put them in a word equation and you swap the ion numbers...

    soo Ca3Co2

  • Thank You sooo much my teacher thinks we already know this, but i seem to be the only one who dosent so i watch this! thank you!

  • I don't understand the part when you take out the positive and negative charges...

  • @Liminouse It's just a step we do to be able to write the correct formula. It means we just "erase" the charge and don't include it when we write out the formula.

    Mr.P

  • I learned so much more listening to this guy in 9 minutes rather than listening to my teacher teaching this for days on days. Thanks for helping me better understand this topic! You're amazing. :)

  • PLEASE HELP!

    at 7:33 how come chloride can only pick up 1 electron?

  • @QSATitr Because it has 7 valence electrons, it can only take in one electron. So you need 2. EX: Say you have like 8 game cases and 7 of the cases are full. You have 2 extra games, and you cant fit those in one container, so you need 8 more cases with one case missing a game to have a case for every game.

  • Comment removed

  • omg i get it!! i was soooo confused and i didn't get all this ionic charging stuff but now its soooo clear. thanks to this guy; i'm now subscribed to this guy coz his videos are awesome!! keep it up!! :D

  • very helpfull im taking chemistry right now in high school and my teacher cant explain for shit

  • @meee2014 lol same, my teach is from Nam.

  • @meee2014 same here lol

    thank god for this guy wish i could talk to him in real life or have him as a teacher lol

  • excellent explanation. 

  • Thank you very much!

  • Comment removed

  • gracias this is tedious

  • Finally someone who can teach Chemistry :) Thnx needed this tutorial

  • Comment removed

  • Amazing job of explaining thanks much

  • AWESOME!

  • Thank you!!!!

  • my HERO.

  • These videos are a god send, seriously my professor is horrible and didnt explain in detail half the things you did thank you so much i am going to watch these everyday until my test! thanks! :)

  • how did you get the charges?

    

  • Thank you so much. You are a better teacher than my tutor, and best of all, you do it for free. The world could use more of wonderful people like you.

  • Thank you!!! I wish you were my teacher!!!:(

  • this is why youtube is my teacher.

  • Though I do have a question, what charge do I give to a transition metal? I am asked to find out the charge for an Iron (III) oxide. Well the oxide is +2 ofc. But what makes Iron -3? I am puzzled. This may be an incredibly stupid question. It could be simple as to say as it has Iron followed by roman numeral 3, but why is it that way? It stumps me XD

  • Why are youtube professors so epic, while my college professors and text books suck so bad? When I am reading this in my book it seems like rocket science. Then I watch this and it is like gradeschool math. =/

  • Thank you so much. literally you have saved me from failing

  • thanks!

  • thank you so much ! I dont understand a thing my science teacher is teaching -__- 

  • You saved my life. Literally. I got an A+ on the test when I probably would've gotten an F if I hadn't watched this video.

  • thank u soooooooooo much my teacher didnt get it thru to me like u

  • bro this vid helped me with my grade 10 science homework

    hopefully u have more videos to help me with my future homework

  • fantastic great good wonderful excellent :DD

  • How do I know the charge of the atom?

  • @TheMaristBoy If you know the trends, such as group numbers representing valence electrons and the concept of fulfilling the octet rule you can identify just by looking at the periodic table as to what the charge is. Example, Group VIIB (7B) are the Halogens (F, Cl, Br, I) they have 7 valence electrons, which means they need to gain one more electron to reach their octet (-1). Group II (2) are the Alkaline Earth metals. They have 2 valence electrons and can lose those 2 to become a +2

  • @Papapodcasts What about transition metals?

  • @testiclecrusher2 I have a video called "Transition Metals". Check it out

  • @testiclecrusher2 They are usually 99.9% +2

  • @TheMaristBoy I have a link for the periodic table my class uses listed in the description. Hope this helps you. Thanks for watching and thank you for the nice words on one of my other videos. Best of luck with your studies.

    Mr.P

  • Thank you so much, that cleared up a lot of stuff and helped me with my hw!

  • Wow, you're very informative, thanks :D

  • hii ! how about videos of how to identify writing formulas. like adding ide, dic, ous and more..

  • You are amazing? I'm taking prenursing courses after being out of school for 25 years.....and chemistry has almost done me in. After classes I've been coming home and going over the material on youtube...and it all starts to make sense...thanks so much!!!

  • Cause of this video i aced a the test

    thanx so much

    

  • @noobboyful You aced the test cause of you. I may have helped you understand but it was up to you to take that knowledge and apply it on your test. All that aside, it's music to my ears to hear people doing well. Keep up your hard work. I wish you all the success in the world. Thank you for those kind words, they mean a lot to me.

    Mr.P

  • Your videos made me realize how easy Chemistry can be. How I wish you were my teacher! Thanks and God Bless :)))

  • I'm just about to start a University Course in Forensic Science, i last did Higher Chemistry in school 6 years ago. Your videos are helping me to brush up before i go. Thanks a lot :)

  • Hi, I'm quite new to Chemistry. I was wondering, where on the periodic table does it tell you the charge of an element?

  • @RyJ2009 I have a link where you can download a copy of the periodic table I provide my classes with. You need to look at valence electrons and identify how atoms achieve their stable octet to figure out charges of various atoms when you are NOT provided with a periodic table that displays them. Check out my video on "Atoms vs. Ions". That should help you. Good luck with your studies.

    Mr.P

  • Thank you so much for this video! This helped me understand a lot clearer and feel more confident onthese problems!

  • @besaesa That's awesome to hear. Being confident with the problems is so important and I'm glad this video helped you with that. All the best with your studies and thanks for the follow.

    Mr.P

  • You make much more sense than my teacher. Thank you! LIKE

  • i have exams tomorrow. what is the basis of knowing the charge?

  • This is very helpful...thanks for sharing

    

  • @diamondfive5 You are very welcome. Thank you for watching. All the best with your studies.

    Mr.P

  • Amazing, thank you.. But how do U find the charges?

  • @rmanutdful You're very welcome. Some understanding of valence electrons and how many electrons need to be lost of gained to achieve a stable octet will allow you to figure out MOST of the charges. Otherwise, download my periodic table link under this video. Hope this helps you.

    Mr.P

  • thats the last time i look in my textbook

  • thank-you sir

  • why go to school if you have @Papapodcasts

  • your amazing. Helped so much.

  • @swaggaboy444 You're very welcome.

    Mr.P

  • I got my science teacher to try teach me this so many times! damn. youtube is so awesome!

  • hey man, I was wondering, have you got a video on structural formulas?

  • Thanks

  • how do u know what charge the element is?

  • @LeBron23Rulz For groups 1,2,15, 16, and 17 you should know their charges. Notice the trend. I do have a periodic table you can download that includes these charges. Check out the link underneath the video.

    Mr.P

  • These lessons are great, they really saved me on my test.

  • sometimes when i look through common ions, and through the periodic table i find words that are similar but with different endings... Some have ate, ite, ide and ium but why are they endings different? what do they mean and do they affect the formulas?

  • @futebalmakedonia You need to go through these videos that start at lesson 1. When you go through all these lessons you will see when to use ide, ate, ite, etc. Good luck with your studies.

    Mr. P

  • Nice lesson!!! :)

    ciao dear Michelino!!! :)

  • These videos can been a great help and im acing my labs but I still can seem to get enough to pass my tests

  • You really helped me so much , you're even better than our Chemistry teacher

    Thank you very much

    and by the way I'm from UAE

    xD

  • nice

  • good teaching skills there

  • Omg, thanks, this is like so helpful, I did NOT get what my teacher meant at ALL, and everyone else got what she meant, so now i finally got what she said using this video, thanks a bunch. :)

  • Comment removed

  • Helped a lot for my test tommoorow for science

    thanks a lot

  • I M sooooooo Thnkfull to u ....its very helpfull for students....excellent ...I m Pakistani...Plzzz more upload more video such that

  • Thankss, :DDDD

  • You're the best. Thank You.

  • How do you determine the charges for each element?

  • oh my god thank you thank you thank you. if only my teacher could teach this as simple as you did.

  • Seriously..... what has happened to the world, a 9 minute youtube education is better than hours of private school education.

  • my concepts are clear

  • wonderful

  • I already knew this.. I guess I wanted to know when to put the brackets in and also more complicated ones as well. Na has a + charge and CI has a negative charge... They cancel each other out. You don't even need to know the cross over rule for that.. Thanks anyway.

  • LIFE SAVERRRRRR

  • I BOW DOWN TO YOU !!!! I was away a science class and my teacher didn't ask me if I wanted to relearn the most important part of the fricking unit. Long story short I didn't understand it until now. Your a great frickin teacher!!!!

  • well i have now came to the conclusion i can get a better education on youtube thank you oh..sooooo very much :)

  • @MsPebbles2010 My science teacher taught us this for a week, and i didnt get it. i watched this video for like 2 minutes and i got it

  • @MsPebbles2010 I was just thinking the same thing...after classes i go home and look up the material on youtube.... :)

  • THANK YOU 

  • @115Sarah115 You're very welcome. Good luck with your studies.

    Mr.P

  • @Papapodcasts

    Hi Papapdocasts, sorry about this but I have a few questions. So why does a compound become positive when it subtracts electrons? shouldn't it be the other way around, it should be negative for losing electrons. Also, how do you know how many electrons a compound can hold? You said that chloride can only pick up 8, is that a rule for every compound? Also how do you know how many electrons a compound has to begin with? Thank you for your time and have a wonderful day!

  • so whenever it's a Binary compound it's always going to be ending with an "ide"?

  • @ShadowMysticWarrior Yes you are correct. There are some exceptions to this rule such as the polyatomic OH- which is called hydroxide. Make note of the ending. CN- is cyanide.

    Examples: lithium hydroxide = LiOH (not binary), KCN = potassium cyanide (also not binary). But, yes, when you have 2 different types of atoms in a formula they will have an "ide" ending.

    Hope this helps you. Good luck with your studies.

    Mr.P

  • thank you sir

  • thank you so much. i am having some trouble in chemistry and your videos are really helping me. congrats you are my savior

  • @extrmemonkey You are very welcome. Best of luck with your studies.

    Mr.P

  • thank you. it makes sense now!!!

  • thank u for this. its a big help

  • your a saint.

  • this guy really helped me i have exams in a weeek and this guy just really lessend my problems thank u

  • OMG THIS IS WHAT I'm LOOKING FOR!! THANK YOU FOR THIS!!!

  • If you have an iron(ii) ion and a phosphate ion, when do you use the brackets when writing the formula, and also how would this be done? Thanks

  • @kevin22GG Check out my video on Polyatomic ions. I go through some of these types of examples. Hope it helps you.

    Mr.P

  • @Papapodcasts Hey thanks a lot! I just watched the video on Polyatomic ions and I found it very helpful. I have a big test tomorrow and these videos you have made gave me a lot more knowledge than i would've learned at class.

  • @kevin22GG im stuck on that too! good luck to me and you haha !

  • what if it was +2 - 4 ? i really need help please and thank you im not 2 sure if its -2 and + 4 please help :), btw does positive actully mean - cuz on Na it said +1 i did'nt really see anything on Na why is it +1? um this question is it @ Mr. P

  • @ApexpredatorCa1 Na is a group 1 alkali metal. Just like Li and K, etc. All of these alkali metals have a +1. They all have 1 valence electron which they are dying to give up to another non-metal. Ca, Mg, are group 2 alkaline earth metals and they all have a +2 charge. They are also wanting to give up those 2 electrons to a non-metal in order for them to become stable. Being stable means they will have an electron arrangement similar to that of its nearest noble gas. Noble gases are in Group 18.

  • @Papapodcasts do you have a tutorial or title for using brackets, in a formula/ name, because the name bracket thing is very confusing :s, Thank you for all of these videos you are making they are helping me so much.

  • @ApexpredatorCa1 yea buddy good luck haha

  • @ApexpredatorCa1 Check out my video on "polyatomics". That's when you use brackets.

    Mr.P

  • what if it was +2 - 4 ? i really need help please and thank you im not 2 sure if its -2 and + 4 please help :), btw does positive actully mean - cuz on Na it said +1 i did'nt really see anything on Na why is it +1?

  • @ApexpredatorCa1 So go to my main page. I have a link for a pretty detailed periodic table which my students use for tests, assignments. Hope that helps you. Best of luck with your studies.

    Mr.P

  • what if it was +2 - 4 ? i really need help please and thank you im not 2 sure if its -2 and + 4 please help :)

  • thank you, im using this to study for my final, thank you thank you thank you, you have saved me!!!!!!!!!!!!!!

  • Okay I liked the video, but how do you combine elements that one of them involves a transition metal? For example, Fe (iron), what is the charge on that?

  • @happybro1 Check out my video called "Transition Metals". That will help you with those types of metals.

    Mr.P

  • when do you write Roman numerals?
