At 5:57, n equals 4 l equals 3, 2, 1, 0 and n equals 5 l equals 4, 3, 2, 1, 0 Don't forget that for "l", 0 IS included

i am in love with the professor omg she is much better than mine prof

[joehunt]

@57.10 That stare!! Amazing lectures by the way.

[ChavisvonBradfordscience]

I love ALL of your lectures!!! I do not go to UC Irvine...I'm just curious about electron configuration because I already know who the atomic nucleus works and I know how the physics of celestial objects work but this is a bit more challenging. Anyway...thank you! :)

57:10 baw dr brindley wasn't playin with their asses lmaooo

[greenrabbit-]

What is the difference between orbital and subshell? thanks

[pretzels]

I'm confused Chromium and Molybdenum don't form 1+ ions they form 2+, but that's not what she said.

[TiNg-nkzt]

why isn't it Cu>Cu+>Cu2+>O->O2- at the end? i thought as you move to a larger shell value, the radius increases

[consitatinschneider]

why i can't view her profile at the website?
she not teaching at uc irvine now?

[PANDORASBOXRELEASE]

lies about the electron spin. you can certainly have two electrons in the same orbital with the same spin. it's called a super conductor.

She's missing the point entirely...it's a poor analogy. In terms on quantum chemistry, we do NOT want to be concerned with position, since Heisenberg's uncertainty principle postulates that to know position, we can cannot know the energy value, and vice versa. Her analogy makes it seem like we're concerned with position, when it is more probabilistic, than anything else. She should have just focused on introducing n, l, ml, and ms, and gone from there.
