Chemistry: Polyatomic ion structures

Help! Understanding some of the common polyatomic ions.

Chances are good that you've been asked to memorize some of these to be able to name common ionic compounds.




Studying these structures will help you see common bonding trends and understand "what's going on" at a deeper level. :)

(I made this video at 5AM, and I didn't want to wake up my sleeping infant.... sorry about the tired-sounding-voice. :) I couldn't help it!)

i dont understand the H3O thing

[TTUchem1010]

I've posted a video "Understanding strong acids" to help you and drkelven2 understand and follow the electrons during the formation of H3O+.

Let me know if this answers your questions

[ultrabunny222]

you kinda fucked up in your example. you gave an example of hydroxide which is a covalent molecule and they can only be ions if you have a metal and a nonmetal together!

just pointing that out =]

[TTUchem1010]

Glad to see you're thinking, but think a little harder & explain this:

When ammonia is bubbled through water, the new aqueous solution will conduct electricity and turn red litmus paper blue.

Hint: Google "hydroxide ion" for help. =]

Hi,

How can I thank you for such an awesome tutorial! Just brilliant!  I was close to crying because I couldn't figure out where the charges were coming from!! This made it crystal clear. Thank you so much!!!!!!!!!!!!!!!!!!!!!!!!!!

God Bless :)

In regards to the H30 compound, I don't fully understand why oxygen happens to have lost an electron.

zomg thank you SO much! you have no idea you really saved the day for me

[vijay24garg]

glad you have posted this video

you should have also given the process of constructing these structures instead of just explaining them

[vijay24garg]

glad you have posted this video

[misterfreehugs]

have you gone over polyatomic cations?

[ScarlettSil]

that is so helpful:)thank you:):)

@paynefanbro too dumb :))

[greent26tube]

You should get outside. The birds are chirping and you can get out and see chemistry in action! Nice video though.

thank you very much for your video, i try to do them as i watch along and i god all of them right after watching 4 videos!!! you are soo amazing! i have exam tomorrow and i am sure i will do soo well on Lewis structures now:D thank you and God bless:D

[LittleCazzy]

Thank you so much for posting these videos, I under stand Lewis structures a lot better now.
