CH10 – Orbital Magic

Dates

• P1 – Monday, September 19th
• P3 – Tuesday, September 20th
• P5 – Tuesday, September 20th

Recap: Electrons

• QN tell us where an electron can be
• 60 possible options on 1st four levels
• 30 orbitals hold 2 electrons each
• Hydrogen simple – only one electron
• multi-electrons alter some energy options
• PT tells us how multiple electrons are filled in an atom
• CONFIGURATIONS tell us shorthand

Orbitals (examples)

• <1,0,0> = 1s
• <2,0,0> = 2s
• <2,0,-1> & <2,0,0> & <2,0,1> = 2p
