hello sir! : i have a question i am really confused between the electrostatic forces of attraction not in the atom it self but between bonds! and cation attracting an anion??? i really did not get this point really confusing! please briefly answer me because everything seems to be mixed up in my mind and thank you! because of you i am doing better in chemistry :)!
On a worksheet that I got for homework, it says to add Roman numerals where necessary, but it isn't explained how to in this video. Some help, please?
Thank you sir, my teacher did this a whole different way. My friend is checking my HW as we always do in class hes gonna be confused because I did it a different way xD
I have a question. With the practice questions, with the last one "Scandium Phosphide", Phosphorus should be P-3 going by the formula, however on the periodic table, it said it is P+3. Why is this?
You have saved my chem grade and I can't thank you enough (but I'll try)!! Thank you for taking the time and breaking down lessons for all of us out here!! You're amazing!! Thank you, thank you, thank you!!!
Thank you for not going "THIS IS THE HARDEST THING IN THE WORLD IF YOU DON'T STUDY EVERY NIGHT YOU ARE NEVER GOING TO GET IT! YOU ARE DOOMED!" That's what my teacher does and it is really discouraging. :c
I don't get it! What is all the stuff with prefixes, and roman numerals, when calcium has 3 atoms and Phosphorous has 2. Wouldn't it be tricalcium diphosphoride?
@Friedwhippedcream You have to look at what kind of compound they are. Are they ionic or covalent? I believe the compound you're looking at is ionic. The roman numerals are if the ion (this is for ionic only) can have several oxidation numbers so you'll write the name of the cation followed by the roman numeral. As for the prefixes, those are used in covalent bonds. So an ionic compound: Iron (III) oxide; Covalent: Dihydrogen monoxide.
@Friedwhippedcream But I don't see why Phosphorous would need two because the outer valence is 5 and the outer valence for Ca is 2. In order to form the octet, the compound would be fine with just Ca3 and one P. And Ca has a +2 while Ph has a -1. The charges of these elements are important in the naming as well.
Please answer a.s.a.p, why is oxygen -1 and -2 i actually dont understand why there is more then 1 valency can someone please explain this to me in detail!
@OmgNomg Oxygen only has a -2. That -1 is not a charge of oxygen and I state that in the video. That -1 comes from the steps I use to go backwards in accordance to "Formulas Lesson 1".
@TheMaristBoy No the charge for oxygen is -2. I did the -1 to simplify the step from the first part of the video. Metals typically can have more than one charge however, non-metals have jet the one charge.
@TheGamekid96 diamond is the toughest material on earth i'm pretty sure of. correct if otherwise because it's used in many industrial construction works. :)
This is sooo much easier than listening to my teacher (who NO ONE can understand) and also easier than asking my classmates. Thank you so much and God bless!
Thanks for the video! My exams are tomorrow and I had a problem with my Chemistry Teacher. She was rambling about things I didn't understand in this topic, even when I ask her to explain it again the WHOLE class doesn't get it. So thanks :D
One problem... Her way is different from yours... Will I answer in your way? :))
Thank you so much! We just "learned" this in class today and have a quiz over it tomorrow- this helped me so much! I wish I found your lessons sooner as I have been struggling in Chemistry for a while now. I can already see my grade rising now thanks to you XD
at the Ca3N2, why is it just Calcium nitride only and then it has no numbers with the name? ty please and answer @ mr . P i love your lessons and videos thank you, Chemistry is the hardest unit right now, and it is really hard.
@ApexpredatorCa1 Hi there. Calcium only has one charge and that charge is a +2. There is no other charge we can mistake calcium for and that is why there is no need to put a number with the name. On my main page I have a link to a detailed Periodic table if you like to print out. It has all the other charges. Look at Fe which has a +2 and a +3 charge. It's a metal (transition) that needs to place a Roman numeral in the name to decipher between the 2 of them. Check out Transition metals. Mr.P
@lakersneedlebron Yes you do but check out my video called Transition Metals. That's the lesson that looks at when to use Roman numerals. Thanks for watching. Good luck with your studies.
@lakersneedlebron Yes you do but check out my video called Transition Metals. That's the lesson that looks at when to use Roman numerals. Thanks for watching. Good luck with your studies.
@xOxPaRiS2xOx The ending is "ide" for binary compounds (excluding acids). Binary meaning 2 types of atoms. I tell my students to "count" the capital letters.
MgF2 - 2 capital letters, binary and ends in "ide"
MgSO4 - 3 capital letters, polyatomic, not an "ide"
However there are exceptions to this last example rule: Mg(OH)2 - 3 capital letters, but the polyatomic is "hydroxide". So you need to learn some of these exceptions. Hope it helped you.
@aildfan08 You are absolutely correct. Look for a metal and non-metal combination. If you have BOTH being non-metals then its molecular. Thanks for watching. Good luck with your studies.
Why dont you follow the 'stock system'? wherein u list the number of the charge of the metal in roman numerals.. example, AlBr3 is Aluminum III Bromide, right?
@lakersownsuns You only use the Stock System for transition metals that have more than one charge. Al has one charge and it is a +3. Check out my video on transition metals. Thank you for your kind words from the other video. I wish you luck with your studies. Go Lakers!
omg this video made it so much easier than my teacher love it.im 29 and havent had chem for many years.i have a quiz tomorrow and was pulling my hair out this made it so much simplier thanks
@ascrysis3 Naming it is the same as all the other ones. It would be called Aluminum Nitrite. For more about these types of polyatomic ions check out my video called "Polyatomic Variations"
@GerardoArwi57 I mention it somewhere in this video that these steps are redundant for such an example (MgO) check 0:19 you weren't listening. My method of teaching is to try to show one method to get an answer and to be able to use the same method consistently. Even though these steps aren't needed, what happens when you get to part 2 (the Transition metals, such as FeO). If students have the first method in their head, then they will answer it as iron oxide and wonder why they got it wrong.
Seems to me to be a little more complicated than it needs to be. You name the cation and name add ide to the cation to name an ionic compound. You also leave out roman numerals on names of cations that can have more than one charge like iron (III). Well explained video on the whole though.
I do discuss the Roman Numerals. These are called Transition Metals. Check out the video on Transition metals. Youtube only allows me to include a 10 minute video. Plus this is just an INTRODUCTION video.
you taught me how to name binary ionic compounds about 60 times faster than i was from my teacher trying to explain it to me today in class, or reading about it in the textbook for the past few days...well several days <_<
your narration and animation and explaining what is happening in real time gives me a visual to remember, and teaches me the process in the snap of my fingers because of how visual of a learner i am.
many thanks! i will surely keep watching your videos, keep up the good work
Thank you so much for taking the time to share your thoughts about my video and how it has helped you. Those kind words are what motivate me to continue to want to make these types of videos. Thank you for your support and I wish you best of luck with your studies. Keep me posted.
I used this response to further back my the in-services where I present to a group of teachers the importance of creating such video tools. Sometimes when you are sitting in class, it may be the last place you'd rather be at that moment. Maybe you have your class first thing in the morning or the last period of the day. With these videos, you are making your own effort to learn something. You are coming onto youtube with a purpose. Thanks for watching.
Yes thank you. I find my teachers to be confusing. My Chemistry teacher right now has a Ph.D. I find it hard for some of these calibur of people to relate to dummies like me lol
Your the best. What I don't understand from my teacher, I can learn from you easily. Thanks for these videos and please continue making them, you don't know how helpful they are.
Magnesium only has 1 charge and so there is no need to put a Roman numeral. You only put Roman numerals with metals that contain more than 1 charge. Example Cu has a charge of a +1 and a +2.
When sulfur gains 2 electrons, it becomes an ion. However, sulfur is a non-metal (right side of periodic table) and non-metals undergo a name change. A sulfur ion is called "sulfide". Non-metal when they become charged change their name to "ide"
Ex: oxygen gains 2 e- = oxide
chlorine gains 1 e = chloride
Nitrogen gains 3e= nitride
I hope this helped answer your question. Let me know. Best of luck with your studies.
okay so this really helped a lot but my question is do we have to go through all the steps if all we have to do is name them? i get the steps and how to do it but whats the point? i did your practice questions and you just named them...well anyone can do that. i guess my question was is the point of the extra steps?
The point of the extra steps is primarily for the Transition metals. The metals in the middle section of the Periodic Table that consist of more than one charge (i.e. Fe+2 and Fe+3)
The reverse steps are to help identify which of those charges, so as long as you only have one charge, such as Mg+2, Na+1, Li+1 - all these examples, just name it. But if you have Cu, or Fe, Mn, Pb, etc, these have more than one charge associated with them.I hope this helped, best of luck with your studies.
i thought the charge of trasitional metals was used witn roman numerals so wouldnt the last one be scandium (III) phosphide. Phas a -3 so scandium would have to have a +3?
Thank you so very much for the kind words. It really made my morning, thank you. I wish you both best of luck with you courses. With regards Scandium, it has a charge of +3. The roman numerals are used to distinguish between 2 or more "different" charges associated with any given atom. An example of this is Iron (Fe) having 2 different charges: a +2 and a +3. We use roman numerals with Fe because there is more than one charge to distinguish with. Have a great week. Mr.P
oh maan, thanks so much for this lecture! my teacher assigned this to a reporter and didnt explain it well, i have exams tomorrow and this will def. help me a LOT! THANKS!
Thank you for all the kind words. I'm glad I was able to help you understand the material a little bit better. I wish you best of luck this coming year. Thanks for watching.
Thanks SO much. My Science teacher didn't teach us any of this. Exams are tomorrow, and the book didn't make sense. You've helped me SO much. Now I actually get this :) Wish me luck. I'm off to watch your other videos now.
I took the test, but its a government one so I wont get it back in a while. i felt REALLY good about doing it however. Thanks so much, you helped me out a ton.
Lol. Thank you for those kind words.They mean a lot to me. All teachers have different styles. Thanks for watching all my different types of videos. I wish you best of luck with all your courses.
I'm surprised that you haven't made a video showing the difference between Acids and Bases. Also for the general rules of the periodic table there are exceptions, so if you were to make a video about acids and bases it would be nice to see the exceptions.
Well thanks for your videos, they're always a useful resource. This may be surprising coming from a student, but I am the type of person who will dig everywhere until I find the answer to understanding the subject. Thanks!
Thanks for watching. The videos I've created are based on our grade 10 curriculum. We touch upon acids and bases, but we only look at the basics (identification of common acids/bases, neutralization rxns, and ionization). With my class I added naming of acids and bases so this way they had a head start on the grade 11 chemistry. So if you are looking for naming of acids and bases I do have a video on it. Best of luck with your studies. Keep up the hard work.
2 metals do not bond together, and 2 non-metals make up a covalent bond. Check out my video on covalent bonds. When dealing with 2 non-metals you don't use the cross over method. Instead, you use prefixes like "di, tri, tetra, penta"
Thanks for watching, best of luck with your studies.
Calciums only charge is a +2 so there is no need for a Roman numeral. Its the transition metals that have more than 1 charge such as Iron, which has a +2 and a +3. The Roman numeral is there only to distinguish which charge to use. I hope that this has helped you. Good luck with your studies.

why we,students can learn easily when we are watching our lessons than listening to our teacher plsss answer me

I used this response to further back my the in-services where I present to a group of teachers the importance of creating such video tools. Sometimes when you are sitting in class, it may be the last place you'd rather be at that moment. Maybe you have your class first thing in the morning or the last period of the day. With these videos, you are making your own effort to learn something. You are coming onto youtube with a purpose. Thanks for watching.

Yes thank you. I find my teachers to be confusing. My Chemistry teacher right now has a Ph.D. I find it hard for some of these calibur of people to relate to dummies like me lol
great vid

I have a question. Don't you have to write the roman numeral number between the metal and non metal?
So for example, MgO final answer would be Magnesium II oxide?
kaitlinforever 2 years ago
Magnesium only has 1 charge and so there is no need to put a Roman numeral. You only put Roman numerals with metals that contain more than 1 charge. Example Cu has a charge of a +1 and a +2.
Thanks for watching. I hope this shed some light.

oh another question i have comes straight from the book. it says: give the name and symbol of the ion formed when a sulfur gains two electrons.
i dont even know what it's asking. ive read the section over ions and ionic compounds a million times and it doesnt make sense to me.
ballerinagirlie 2 years ago
When sulfur gains 2 electrons, it becomes an ion. However, sulfur is a non-metal (right side of periodic table) and non-metals undergo a name change. A sulfur ion is called "sulfide". Non-metal when they become charged change their name to "ide"
Ex: oxygen gains 2 e- = oxide
chlorine gains 1 e = chloride
Nitrogen gains 3e= nitride
I hope this helped answer your question. Let me know. Best of luck with your studies.
Mr.P
Papapodcasts 2 years ago
yes! thank you so much.
ballerinagirlie 2 years ago
okay so this really helped a lot but my question is do we have to go through all the steps if all we have to do is name them? i get the steps and how to do it but whats the point? i did your practice questions and you just named them...well anyone can do that. i guess my question was is the point of the extra steps?
ballerinagirlie 2 years ago
The point of the extra steps is primarily for the Transition metals. The metals in the middle section of the Periodic Table that consist of more than one charge (i.e. Fe+2 and Fe+3)
The reverse steps are to help identify which of those charges, so as long as you only have one charge, such as Mg+2, Na+1, Li+1 - all these examples, just name it. But if you have Cu, or Fe, Mn, Pb, etc, these have more than one charge associated with them.I hope this helped, best of luck with your studies.

how would you name Fe4(Fe(CN)6)3??
oxijen22 2 years ago
this one is not possible, double check your question

This video has helped me alot. I am behind in my Chem 131 class. Is there a video on here involving the roman numerals? I hate trouble with that
oatmealpizza4u 2 years ago
i thought the charge of trasitional metals was used witn roman numerals so wouldnt the last one be scandium (III) phosphide. Phas a -3 so scandium would have to have a +3?
DnugAirwalker 2 years ago
Thank you so very much for the kind words. It really made my morning, thank you. I wish you both best of luck with you courses. With regards Scandium, it has a charge of +3. The roman numerals are used to distinguish between 2 or more "different" charges associated with any given atom. An example of this is Iron (Fe) having 2 different charges: a +2 and a +3. We use roman numerals with Fe because there is more than one charge to distinguish with. Have a great week. Mr.P

After 2 semesters of chemistry I still didn't get Ionic compounds, yet it took only one of your videos for me to get how to do it.
You're truly amazing.

I'm surprised that you haven't made a video showing the difference between Acids and Bases. Also for the general rules of the periodic table there are exceptions, so if you were to make a video about acids and bases it would be nice to see the exceptions.
Well thanks for your videos, they're always a useful resource. This may be surprising coming from a student, but I am the type of person who will dig everywhere until I find the answer to understanding the subject. Thanks!
Goal2Tend 2 years ago
Thanks for watching. The videos I've created are based on our grade 10 curriculum. We touch upon acids and bases, but we only look at the basics (identification of common acids/bases, neutralization rxns, and ionization). With my class I added naming of acids and bases so this way they had a head start on the grade 11 chemistry. So if you are looking for naming of acids and bases I do have a video on it. Best of luck with your studies. Keep up the hard work.

What if its two metals? Two non- metals?
Ebay4everyone 2 years ago
Hey there,
2 metals do not bond together, and 2 non-metals make up a covalent bond. Check out my video on covalent bonds. When dealing with 2 non-metals you don't use the cross over method. Instead, you use prefixes like "di, tri, tetra, penta"
Thanks for watching, best of luck with your studies.

im confuced isnt it Ca (II) Phospihde?
soulxofxgirl 2 years ago
Calciums only charge is a +2 so there is no need for a Roman numeral. Its the transition metals that have more than 1 charge such as Iron, which has a +2 and a +3. The Roman numeral is there only to distinguish which charge to use. I hope that this has helped you. Good luck with your studies.
