Date

• Friday, October 27th

Recap Last Class

• how many orbitals are in each subshell? (s, p, d, f)
• how many electrons can fit in an orbital?
• how many electrons can fit in a subshell? (s, p, d, f)
• how many electrons can fit in energy level 1? 2? 3?

New Idea – Orbital Diagrams

• lay out orbitals
• fill the electrons
• how does filling work?

New Idea – Electron Configurations

• shorthand notation
• order of filling

New Idea – Using the Periodic Table

• is there a pattern?
• how does it relate?
• Use PTable! [LINK]
