If Bohr was wrong about orbits, then what do these energy levels REALLY look like?

Today's Lesson.... Electron Hotels! Do Now: How many electrons are in the following atoms? 1 e- 1) H 2) Be 3) N 4) Ar 5) V 4 e- 7 e- 18 e- 23 e-

So what does an electron hotel look like? There are four types of suites: Simple (s) Posh (p) Deluxe (d) FANTABULOUS (f) --- 1 room --- 3 rooms --- 5 rooms --- 7 rooms

Obviously, e- don’t really stay in hotel rooms… 2p 2s 1s CORRECT VOCABULARY Floor = Principal Energy Level Suite = Sublevel Room = Orbital 1s22s1 Li

Hotel Layout... 3d 4s 3p 3s 2p 2s 1s NOTICE!

The electrons' habits.... e- are always moving so they stay in hotels. When e- enter the hotel they're lazy! (they avoid climbing the stairs at all costs)‏ e- like privacy and prefer to stay in a room all alone, but... if they have no choice, an e- will share a room with 1 other e- - maximum! When sharing a room, an e- will always ignore the other e-.

Example #1 ... Hydrogen 3d 4s 3p 3s 2p 2s 1s H has 1 e- That electron is lazy and stays in the first open room it finds! 1s1

1s22s2 Example #2 ... Beryllium Be has 4 e- 3d 4s 3p 3s 2p 2s 1s Be has 4 e- Those e- are also lazy and stay in the first open rooms they find too! 1s22s2

1s22s22p3 Example #3 ... Nitrogen N has 7 e- 3d 4s 3p 3s 2p 2s 1s N has 7 e- Those e- are also lazy and stay in the first open rooms they find too! 1s22s22p3

Maximum Number of Electrons In Each Sublevel In Each Suite Type Maximum Number of Electrons In Each Sublevel Suite # of Maximum # Type rooms of electrons s 1 2 p 3 6 d 5 10 f 7 14

So how am I supposed to remember the order of the rooms? MUST BE Ag! What element would this be? 47 total e- Ex: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d9
