Atoms vs. Ions

[bbauer2008]

I don't understand. I thought the 3rd shell could have 18 electrons not 8? N=2 x n^2.

[gogirlz99]

THANK YOU!!!!!!!!!

[gogirlz99]

this is awesome. 

[sugarliciousXD]

have i ever told you how much i love you lol jk i dont but thank you!

[Trashcansam123]

I have finals in 2 days. Thanks for help.

[Yapiej]

I seriously could not concentrate for my test tomorrow, listening to you really helps THANK YOU! :D

[zoombalaboy]

I'm 12. Why am I watching this?

[1Nekit1]

Thanks!!!

[EmOhLee12345]

This is seriously so helpful!

[eelinelin]

im trying to understand why the ion loses the dots?

[Papapodcasts]

@eelinelin They try to achieve a similar electron arrangement as their nearest Noble gas as the Noble gases are the most stable atoms on the periodic table.

[TheTomp224]

@eelinelin lol those dots are electrons

[TheCalimbaKing]

Metals can only be positively charged. If they are, they are considered ions called 'cations'. Non-metals can only be negatively charged. If they are, they are considered 'anions'. Am I getting this right? It's really late, and I wanted to see how much I could comprehend half-asleep.

[1nunukurdy]

well done... thank you



[123etobes]

COULDNT LEARN THIS IN GRADE 9 IM IN GRADE 10 AND I JUST LERNED IT NOW!!! THANKS

[TheMaristBoy]

@Papapodcasts amazing. When I have questions, my teacher would shun them back to me. But with you I don't even have questions. I feel like crying now :''''(

[TheNigahigaSmoshfan]

thank u so much i'm in the 8th grade and we did this in classs except my teacher is.....well terrible. this actually helped me understand the topic :)

[nala931]

this is seriously more than i learned in a week. thank you so much mr. p!!!!! youre awsome

[Papapodcasts]

@nala931 Thank you so much. I appreciate you watching and commenting. Good luck with your studies.

Mr.P

[Chalron]

Thank you soooo much. Your teaching video has been very much appreciated and has helped me immensely. Agree with CascadeSeven61 - you are a lifesaver!

[ametasutaiyo]

The remember the "T" as a positive is genius.

I would've thought "Cat's are positive" xD

[clockwise3559]

does an ion have the same properites as its atom counter part when floating in a solution by its self?

[faithite]

i thought its "2-" not "-2" which one isit? :) for example Mg2+ or Mg+2?

[Papapodcasts]

@faithite Doesn't really matter. Find out how your teacher wants it. Ask them so this way you do not lose marks. Personally it doesn't really matter to me. Thanks for watching.

Mr.P

[imadude55]

i <3 u, have quiz on exactly this and periodic table.

[Mikeyrenk]

i understood this better than the shit my teacher teaches..... r u like a college professor or something?

[jackxzx]

how to determine the charges directly from the periodic table?

do you have a video explaining thaT?

thanks a bunch!

[Papapodcasts]

@jackxzx Thanks for watching. A periodic table can be found on my channel page, scroll to my profile and there will be a link to a google doc. This is the periodic table I use with my class. Hope it helps you. Good luck with your studies.

Mr.P

[chirowebguy]

Thanks!! You help take the mystery out of chemistry!

[EngrossingEnigma]

Calm collected and understandable instruction about ions everything I was looking for. thanks a million.

[vasavipandey]

for sulfur wouldn't it be possible to lose 2 electrons in the outer shell? to balance out and have a total of 4?

[Papapodcasts]

@vasavipandey unfortunately not. 4 electrons is not a stable electron arrangement.

[LOSTRONERD]

why do u gain 6 electrons when you have 2? arent the energy levels 2 8 18? please reply fast i have exam tomorrow lol

[Papapodcasts]

@LOSTRONERD Please goes a long way....watch the video carefully, we don't gain 6 electrons

[ParaDICEcinema]

@Papapodcasts

What do you do if you have 2.8.4, do you remove 4 or add 4?

[Papapodcasts]

@ParaDICEcinema 4's always form covalent bonds.

[ParaDICEcinema]

@LOSTRONERD

Its remove 2 to make it stable, if its 2.8.1 or 2.8.2 or 2.8.3 you remove the last number electrons 1 or 2 or 3.

But if its 2.8.5 (to) .7 you add the amount you need to make it 8. but if its 4. your lost as you don't know whether to add or remove.

[jakeleppy]

@LOSTRONERD its 2,8,8 in gsce corse

[misafan4u]

omfg... dude thank youuuuuuuuuuuuuuu so much, i finally understand how the canion and anion charges work

[Papapodcasts]

@misafan4u I'm glad I was able to help. Best of luck with the rest of your studies.

Mr.P

[JUST2AZN4U2]

basically think of giving = positive  stealing/taking = negative

giving is a "positive" thing to do!

stealing/taking is a "negative" thing to do!

[Papapodcasts]

@JUST2AZN4U2 That's pretty much it. Good way of interpreting it. Good luck with your studies.

Mr.P

[MsIdontmakevideos]

im so confused about chemistry. im doomed tomorrow, doomed i tell ya!

[crescine]

i wish you were my teacher. XD

[puppilove1996]

I'm in grade 9 (i'm from canada so in the state's i'd be grade8) but i do it in french :3

[Papapodcasts]

@puppilove1996 I'm also from Canada. Toronto to be exact. Wow, so you're doing this through a French immersion. Must be tough. Good luck with your studies. Thanks for watching.

Mr.P

[jobomafo]

i dont understand why it was to loose or gain electrons

[echoes19671969]

@jobomafo It's because they needs 8 valence electrons to be stable. It's called the octet rule! :)

[Conzillla]

You rock - thanks for the recap 

[julianna030914]

This helped me very much.. Thank you!!!!

[brittneew]

where have you been this semester?? thank you.

[banucarita]

SO MUCH HELP. SO WELL EXPLAINED! THANK YOU SO MUCH! Nevertheless, ha ha! I was wondering.... what if your atom would either have to loose 4 electrons or gain 4. Which would you choose?

[typicalchue]

Thank goodness for youtube. I now get it. :)

[MrBbarber190]

how do you know it gains or takes aeay

[Papapodcasts]

@MrBbarber190 Metals lose electrons and non-metals gain them

[MrBbarber190]

@Papapodcasts Are you saying non metals like air or water gain elecrons while metals like irons lose electrons? And if so,is this how wind mills cunduct electricity?

[Papapodcasts]

@MrBbarber190 No, air and water are both made of non-metals atoms that share electrons and thus do not create positive and negative charges. Wind mills conducting electricity is more of a physics concept rather than a chemistry concept.

[Papapodcasts]

@MrBbarber190 Table salt is NaCl. The Na loses an electron to Cl. Na becomes + and Cl becomes -. That attraction b/w + and - is what creates an ionic bond. It doesn't exactly conduct electricity until you dissociate it and form an electrolytic solution. Check out electrochemical cells.

[MrBbarber190]

if that wer true copper could cunduced electricity by itself

[Papapodcasts]

@MrBbarber190 We're talking about when they form bonds what happens. They don't just magically lose electrons. We cannot isolate just 1 atom like this. You need to look up some of the material leading up to this lesson. It appears you are struggling with some of the previous information you need leading into this lesson.

[periwinkle16]

your a lifesaver! Thank you!:D i've been struggling with this for the past week,and you made it better to understand. so thanks(:

[roller237]

Awesome. My Bio teacher was killing me with this.. You even included Bohr's diagram which was very helpful. Thanks alot!

[5tonyvvvv]

The atom is so incredibly complex,,we dont know why they have spin as protons and electrons move...we are finding smaller spinning motors inside these parts,called Quarks...but to the evolutionist this can all be explained..whats lies.and there is no intelligence behind this..i find cells and atoms concrete proof of intelligence

where is this information coming from???

[rhenn11]

how do we know if an element is stable or not? o.o sorry, im new to chemistry.

[Papapodcasts]

@rhenn11 Hey there. If you look at each atom on it's own (by itself) they usually don't exist. Oxygen is not just O, it's O2, because O by itself is not stable. So you can almost look at all atoms on the periodic table (except for the Noble gases) as unstable when they are by themselves. They usually require them to form bonds with itself (like O2) or with other atoms like Na2O.

Hope this helped you.

Mr.P

[rhenn11]

@Papapodcasts: ahhh...so that's why. Thanks!

[WHIREAS]

@Papapodcasts But ... How can you do this WITHOUT looking at the periodic table? xS

[chotuzwazzz]

Thanks Thanks Thanks thanks bro :)

i'm weak in study your videos Help me too Much :D

Agian Thanks XDDDDD

[GravityFoxx]

Wait, I'm a bit confused. So the P shell holds 8 or 6? I was taught k shell holds 2 and p holds 6. Also, take sodium for example, what happens if it doesn't become stable and loose the one electron?

[Papapodcasts]

@GravityFoxx You are correct. This video is based on a Bohr-Rutherford model and not a quantum model which consists of the s, p, d, f orbitals. This video is for introductory chemistry

[sickcombos]

@PapapodCcasts please please Mr P can u upload a video about radioactivity?

[sickcombos]

@Papapodcasts plz i want to know how sodium lose electrons?when it react or by itself?

[Papapodcasts]

@sickcombos it can only react when given the need to react. It remains as a solid on its own. But when combined with water it reacts violently. When it reacts with a non-metal, it gives up it's valence electron.

[TheFarhan18]

Thank you . It really helped me . Great work !

[Cohortrohoc]

Nice video. If someone has a moment of anxiety and someone next to them feels it like a wave of anxiety hitting them does that have anything to do ions? If not then what is the wave that the person emits made of? Protons? Neutrons?

[belatoca]

how come the second shell have 8 electrons?its not 6?

[Papapodcasts]

In a simplistic Bohr Rutherford model there are 8. But if we look at it according to energy levels, yes there would be 6 electrons in the p-orbital - note how the s shell has 2 plus the 6 in the p that equal 8 for the second energy level.

Mr.P

[mice88]

it that EASYY!!! jeez my teacher SUX!! THANKZ!

[Papapodcasts]

It really is that easy! Good luck with your studies.

Mr.P

[livelaughlove1115]

OMg thanks sooo muchhhh yur the best i love your explanation and everything is so clear yourrrrr my herooo

lol

that helped me a tonn!!

[ylrobles7]

Thank you for taking the time to do this. You are really good in explaining it (unlike my professor) you are helping alot of us : )

[lkb94]

which one should i watch next ? :S

[jessiestustu]

I'm in Microbiology right now and am totally lost so I"ve had to go back to the basics and let me just say this has helped me so much. I've never heard anyone explain something that was once to complex in my mind so easily. I totally wish my professor was like you!

[Papapodcasts]

I'm glad you found my video helpful. Thank you for those kind words. It's people like you who motivate me to continue creating these videos, who share their kind words. I wish you best of luck with your Microbiology. Thanks for watching.

Mr.P

[borderperson19]

Im taking Chemistry and a bit confused @ 1:09, when you said that "in order for it to become stable" isnt it already stable being that it has 11Protons and 11 Electrons.Should it then be electricaly neutral? Could you clearify that for me.

[Papapodcasts]

Yes electrically they may seem stable having the same number of electrons as protons, but stability is more on the valence electrons. The outer most electrons. Atoms tend to want to have a full valence so metals with lose the outer most electrons because their inner electron shells are full, while non-metals are close to filling their valence shell so they like to add electrons. Hope this helped. Good luck with your studies.

Mr.P

[prissyroel]

Thanks so much for helping me understand science ,my quiz is on friday and from what i have learnt from you im ready for the quiz .

big hug from me .Thanx

[CascadeSeven61]

You are a lifesaver!!!!!!!!!!!!!!!!

[Canabbseser]

Thanks so much! This helped me a lot! I have a science exam tommorow and didn't exactly understand how to do these stuff but this really helped :)

[bananasuberoo]

this is very helpful, thankyou!!

[imarchello]

why are normal atoms considered 'unstable'? how do they express that instability?

[Papapodcasts]

Thanks for watching. Normal atoms at a neutral state crave a complete valence shell. The most stable compounds on a periodic table are the Noble gases and that is because they have a complete valence shell. All atoms crave to reach that kind of stability.

I hope this has helped, best of luck with your studies.

Mr.P

[McLuvin411]

ok, well how are the valence electrons lost?

[Papapodcasts]

They are lost when combined with compounds that are craving to gain valence electrons. Look up electron affinity and ionization energy to understand more on the reason atoms crave electrons and crave to lose electrons. Good luck with your studies.

Mr.P

[KristinaM369]

this is helping out to study my science test that I having soon, thanks:)

[Papapodcasts]

I'm glad I was able to help you. Thanks for watching and best of luck with your studies.

Mr.P

[antonfatso]

tyvm. it helps a lot. just one question:

wheres the vs??? i thought this was telling us the difference in usage or something!

[Papapodcasts]

The vs is more on distinguishing how to use the appropriate terminology. For example, if you are asked to draw a sodium atom or a sodium ion. One will have the valence of 1 electron, while the other will have a charge of +1, because that one electron has been removed. I hope your schooling is going well. Sorry for the late response. Thanks for watching.

Mr.P

[littleAE86thatcould]

my teacher sucks at teaching this... really. one dumb students asks her a question of-topic and then she starts to explain for like 15-20 min. Its difficult for me. But this vid helped. Thanks!

Ohh, and By the way you where using a smart-board correct? LOL

[Papapodcasts]

All us teachers have our own unique styles. I'm sure some of my students don't like my style. Thank you for watching and yes I am using a smartboard, which limits me to creating a lot of these videos at work either afterschool or in the morning. Good luck with your studies.

Mr.P

[sidewaysfcs0718]

so basicly an ion is a charged atom ...with needs to loose or accept electrons to reach a stable structure.

right?

[Papapodcasts]

Yes you are correct. Thanks for watching.

Mr.P

[tomblybo0]

this is fantastic thank you lots I was sure I was going to fail my chemistry test but this has really helped! :)

[zanpaktuh]

What the Faaantasic!!, this took me several days to understand with my stupid teacher and right now it just took my a couple minutes. Thanks dude really thanks a lot, are you a teacher in heaven?? seriously.

[breakfastjak]

My instructor lectured on this exact topic and I did not understand much. Watching this video helped me greatly. Thanks!

[evolagenda]

where do the electrons come from and go that are lost and gained?

[evolagenda]

no wait I've kind of guess that gains are taken from losses and vice versa, so what gives the atom the power to discard it's electron if the orbits are complex and unchangeable without consiquence then why would it "want" or why would it be required that it discards them so?

[hydrid31]

they gain and lose electrons in chemical reaktions.

Na + Cl --> Na^+ + Cl^- --> NaCl

Here Na loses an electron to Cl and Cl gains an electron from Na. Electrons are never just away or suddenly there. It always has to be the same number of electrons in hole.

hope it helped you

[JACKRULES11]

I'm an 8th grade student here and we learned about everything you are stating... just you teach this stuff better then my teacher, who just gives us quizzes on stuff she dosn't teach

[Papapodcasts]

Thank you for watching. As I mentioned with someone else, all us teachers have our own definite style of teaching. I wish you all the best with your studies. Have a great summer.

Mr.P

[BIGBOARUFF]

if anyone has any earphones use them it sounds better!!!!!!!! I am listening to the video right now so it might be better for u f u got earphones thx Again Mr.P

[Papapodcasts]

It's funny because I'm listening to this video right now and the sound is clear on my computer. Mind you it's slightly lower in sound than my other ones. Thank you so much for watching and putting a positive twist on the negative part of this video (the sound). Best of luck with your studies.

Mr.P

[Allen913369]

i think u miss the bracket outside the atom to show it`s an ion.

[Papapodcasts]

The purpose of my lesson is to be able to understand when you have an ion and an atom. The brackets are not as important because they are used mostly for aesthetics. Thank you for watching.

Mr.P

[greeno155]

so sodium only (Na) has 11 electrons and protons but 12 neutrons??

[Papapodcasts]

YES, only if the sodium atom is neutral. The number of neutrons is calculated by subtracting the Atomic Mass with the Atomic number. Sometimes the neutron count will match the number of electrons most of the times it doesn't especially with atoms beyond the second row of atoms. I hope this was helpful. Best of luck with your studies and thanks for watching.

Mr.P

[Allen913369]

explanation: To get neutrons for (Na) subtract proton number from neuclons number.

[elenachg]

Thanks x this lesson! Now I understand more....

[Papapodcasts]

Thank you for watching. I'm glad I was able to help you. Good luck with your studies.

Mr.P

[Brutaleris]

lol first class chemie :)

[Papapodcasts]

Thank you for watching. Best of luck with your studies.

Mr.P

[AeroDesk]

Good work! except that your voice is too soft. Please speak louder.

[Papapodcasts]

Thank you for watching.  Sorry you had problems listening to the lesson. These lessons were originally created for iPods and so on an iPod they sound perfect, not on computers. Best of luck with your studies.

Mr.P

[tuffan99]

i understand cation and anion

its great.

[Papapodcasts]

Thanks for listening. Happy New Year and best of luck with your studies.

Mr.P

[Sunfield4now]

so what technically is fluorine if it is not a metal, just so i know. (GREAT vido btw)

[Papapodcasts]

Fluorine is on the right of the aluminum ladder, so it is considered a NON-METAL. Also it is part of Group 17. Atoms in this group are considered Halogens and contain 7 valence electrons. Check out my video on Groups of the Periodic Table and Anatomy of the Atom for more on the different atoms of the Periodic Table. Best of luck and thanks for watching.

Mr.P

[TheBetafish]

your vids r so perfect to help me study with the chapter we are doing in science right now. thanks for explaining it so well!

[Papapodcasts]

Thanks for checking me out. Best of luck with science and let me know how I can help.

Mr.P

[wichywashy]

Thank you! for explaining this :D

[Papapodcasts]

You're very welcome. Best of luck with your studies.

Mr.P

[joeyfung85]

thanks...this is a great video...it helped me lotz..
