12:41:36 From Stephanie Day : Aufbau: Fill electrons from lowest to highest

12:41:46 From Stephanie Day : Hund's Rule: Spread out before pairing

12:42:20 From Stephanie Day : PAuli Exclusion: max of 2 electrons with opposite spins

12:42:39 From Stephanie Day : each electron get represented with an arrow

12:43:12 From Stephanie Day : (We won't be drawing orbital boxes this semester, but this helps- PROMISE!

12:43:25 From Stephanie Day : S = standard room (1 bed) 2 ppl

12:43:42 From Stephanie Day : P = premium room (3 beds) 6 ppl)

12:43:58 From Stephanie Day : D= deluxe room (5 beds) 10 ppl

12:45:14 From Stephanie Day : You are my assistant ;)

12:46:19 From Stephanie Day : The analogy:

Energy Level = Floor

Type of Room = Subshell (s, p, d, f)

Orbitals = beds

12:48:05 From Stephanie Day : Energy level 1, max of 2 electrons (s)

Energy level 2, max of 2 electrons (s, p)

Energy level 3, max of 18 electrons (s, p, d)

Energy level 4, max of 32 electrons (has s, p, d, & f)

12:48:34 From Stephanie Day : sorry for that noise

12:49:43 From Stephanie Day : Lobby floor = Nucleus

1st Floor = 1st energy level

2nd floor = 2nd energy level

3rd floor = 3rd energy level

12:51:54 From Stephanie Day : Like the "bus analogy"

12:52:06 From Stephanie Day : You spread out BEFORE sitting with someone

12:52:51 From Stephanie Day : You can fill this in on the Hawk's Hotel Wkst

12:53:13 From Stephanie Day : Found here: https://d358g57815banh.cloudfront.net/3E4uZ2Zf8HP3X_Ce5E63UL6GA7442N2.pdf

12:53:37 From Stephanie Day : Two "electrons" got a bed to themselves :-)

12:54:04 From Stephanie Day : This is called the long hand electron configuration - this is what you'll be doing

12:54:19 From Stephanie Day : This is the shorthand electron configuration - you will also do this

12:54:57 From Stephanie Day : I'll show more examples after this. There is also a video where I do all of Part C with you.

12:55:23 From Stephanie Day : Here is that link:https://youtu.be/MBMRVPMqlaM
