electron” atom. Magnesium, Z= 12, is a “two-electron” atom. Write down its

ground state configuration and possible term values.

i think i get the right answer but I am having a couple of issues:

my answer:

ground state configuration: [Ne] 3s^2

possible term values are for the spin multiplicity either S = 1 or 0 so 2S+1 = 3 or 1

L = 0 therefore = 0

therefore J = 1 or 3

however I am inclined to go with J = 1 as i think the exclusion plays a role.

p.s. ill happily clarify anything here as i know its not the clearest, i just don't know how to wrie term/spectroscopic notation in latex/html

cheers

i just find this term symbol stuff abit cinfusing
