I. •Write orbital notation for C

•Total number of electrons

•Number of electron pairs

•Number of unpaired electrons

•Number of electrons in the outer shell

•Number of electrons in the inner shell

•Outer electrons in energy level__

# Electrons in 2p; #electrons 3p

now, repeat for P

III •Write the electron notation for Se

•# e in 4s

•#e in 3d

•In what energy level are the outer e

•How many electrons in the outer energy lev.

IV •Write noble gas notation for Se

•Number of electrons in the [noble gas]

•Number of elcctrons in addition to the n.g.

•#e in the 3d

•#e in the 4p

V •How many energy levels in Au? # Outer e?

•Repeat for In

VII number of orbitals in s sublevel; number of electrons possible; same question for p, d, and f sublevels

VIII what are the 4 letters that represent 'quantum numbers'? match with energy levels, sublevels, orbitals, and spin (see notes or text)
