Amazing as always! Thank you

Thanks! Favorited. Need to watch it a few more times before my test next week, though.

OMG. Helooo. The CA in caion is catod and the AN in anion is anod. DUDE

Neon says “I’ve achieved happiness in life, don’t mess with my electron”–lol

You’re right, it should be called cationization – historical science can always be brushed up on (as the model of the atom changed throughout the years.)

This is an amazing video and is very intuitive. The more you watch this video, it just gets more and more intuitive each time. This video is absolutely remarkable and really is another one of those big videos that gets your mind opened up to an entire field of new concepts. Lol I know Im saying this for a third time now but I just have got to say though man that this video is absolutely amazing. Great job Sal.

Thank you soooo much! this was a huge help.

can someone plz help me. i need this for an exam in two days.
r the s,p,d orbitals like different shells in the atom. ???

you’re amazing. thank you so much. omg.

tanx 4 dis lecture..am grateful

Ahh i see. Thanks.

Lol, how I think of it is, it’s losing 2 negative charges (’cause electrons are negative) so it’s like… losing a negative, which is positive. So it becomes positive.

It’s easier for them to lose one electron (so that they’ll reach a valence of 8 electrons in the previous energy level). He covers it in the video before this one.

You just saved me from failing at life
il ove you

the energy required to remove 1 electron from 1 mole of gaseous atoms to make 1 mole of gaseous unipositive ions

Why do they want to give away electrons on the first group.
I thought that that group wanted to gain electrons (to reach

very good.

awesome

electrons are negatively charged bud =)

I thought of the same. But you can think of it like this… Say you have Magnesium. Magnesium has 2 valence electrons. Since it has 2 valence electrons it will want to lose 2 for it to become “stable” thus, forming an ion. It would be written as Mg 2+ Think of it like it loses 2 electrons so Magnesium has more Protons now, since it lost 2.

That guy was creating new molecular structures that would become the structure of new medications.
It would take 14 years just to complete the whole process.

Why isn’t #87, Fr, an alkali?
Those ions remind me of when I was getting Couples Therapy w/ that chemist. The therapist told us we were like 2 negative ions, b/c we couldn’t get along, that we canceled each other out.
When we got back to the car, he burst out laughing.
I asked him what was so funny, b/c I found her comment depressing.
He told me negative ions don’t do what she said.
I had no idea they didn’t. I failed high school Chemistry.
Now I’m beginning to see why he laughed.
