Pass Forward Lab 10
HW: Finish Electron Hotel Orbital Diagrams
ONLY not the Electron Configuration Part!
CHECK POWER SCHOOL!!!
**Pick up 4-5 Colored Pencils**
10/21 CQ:
What is a line emission spectrum, what
happens to the atoms’ electrons that allows
us to see it, why is it useful?
The Electron Hotel
Construction Rules
• Mr. Pauli:
– Every room must have bunk beds
• Mr. Aufbau
– Must fill bottom floors first before top floors
• Mr. Hund
– Must fill top bunks before bottom bunks

Connection to the Atom!
This analogy represents:
Where electrons are located AND
how electrons fill orbitals!!
• Floors = energy levels
• Rooms = sublevels
– 4 types of sublevels (s, p, d, f)
• Beds = orbitals in the sublevel where
electrons are located
– 1 orbital = 2 electrons! LIKE 1 bed = 2 people
