Junior Chemistry: Chemical Bonding 1

[lanark2008]

Thank you.. Are you a science teacher?

[san00049]

and thank you.. you are an amazing teacher.. =)

[EliteLennon117]

why is it at school almost all chem teachers suck but on the internet they make sense.

[nexypointy]

thanks sir!

[gemtotherescue]

Thank youuu! ;)

[99luckysam]

I am trying to study chem....

Can you please provide a recommend list or sequence of your videos..... kind of like a play list ....

[DmxCrazy]

[bannanaiscool]

@DmxCrazy On my website!

Chemguy

[pooran411]

Thank u so much!!

[skyuppercutt]

I want to watch all of his videos starting from the very beginning, because I am lost in chemistry. Which video is the fist one?

Thanks :D

[x15justice]

That was a great help, thank you 

[light7est]

Actually the correct difference in electronegativty to consider it a Ionic bond is 1.7 not 1.9 tehe just felt like stating that

[rroyarae22]

Lol PPartially PPositve End

[bannanaiscool]

@SuperSlayerX Not this one. All the ones at my website!

Chemguy

[sickcombos]

@bannanaiscool ok, if two hydrogen atoms bond together for example, then the force of attraction is covalent ok, but if a bunch of hydrogen molecules come close or when these hydrogen molecules are in solid state, how then they are held ?

[bannanaiscool]

@sickcombos LDF.  See intermolecular bonding!

Chemguy

[sickcombos]

plz answer for me this question:

ok..if i am having a piece of Na and i want to react it with chlorine,

first the sodium atoms(before reacting with chlorine)would have lost its electrons.ok when i react it how then how it give to chlorine the electrons if it already lost them ..plz try to understand me and answer me!

thanks.

[bannanaiscool]

@sickcombos No. The sodium doesn't lose the electron as such... the chlorine takes it away!

Chemguy

[sickcombos]

@bannanaiscool but i heard that metals(sodium) lose electrons in a sea of free electrons

[nichjanderson]

@ God hey

[ilovekoreanos]

YOU'RE SUCH A GREAT TEACHER :) THANK YOU SO MUCH!

[brucerd1]

very helpful but what happens when you have a molecule which has both polar and pure covalent bonds like CH2Cl2. Does it behave like a polar or non-polar molecule?

[bannanaiscool]

@brucerd1 Polar!

Chemguy

[xxHoldenxCaulfieldxx]

THANK YOU THANK YOU THANK YOU... my chemistry book loves to find the hardest way to explain something, but you just broke it down to the basics! i really appreciate it, it was a monster help on my test!

[banandababa]

Wheres part 2? help!

[eatmorchikin12]

Thank you so much! These videos are great

[paintitvegan]

Thanks great video!

[SpinningJennifer]

you re reeeallllyyyy helpful ....i totally get it now...thanx

[distefanodude]

A+ lesson. thanks man

[AlishaChild]

What does the writing say about Electronegativity at 1.10?

[thaitanium2005]

@AlishaChild

example: Na + Cl

EN of Na is 0.90

EN of Cl is 3.15

the different is 2.25 > 1.9 so this is a ionic bond

[AlishaChild]

@thaitanium2005

I understand that part, I just couldn't decipher what the writing said that's all. Thanks anyway. :)

[MusicMarionette]

Thanks for helping me with my chem 20 final!

[ragsag211]

wow your really helpful , hopefully my C will go to an A* , thanks alot !

He has a website you can donate at. With the amount of help I've gleaned from these videos I felt it was only fair I threw some cash his way.

[Gilliannn1]

[Gilliannn1]

*raises hand* so if i were to rub a plastic rod through my hair, would it work the same way as it did in this video?

[hailleymari]

I love how you just start talking about chemistry and don't do a long introduction. Refreshing. Also, this will help me pass my chemistry exam tomorrow, so thank you very very much, I wish you taught my chemistry class. :)

[DarthXboxian]

You don't know what you have done for me, a thousand thank yous and god bless you man, keep it up. You are a hero!
