M-3 C1: Spectroscopic Notation using the Periodic Chart  18 Points

Given the Element’s Atomic Number, use the Periodic Chart above to write the Spectroscopic Notation for the following elements.. You may do it the long way showing all blocks of orbitals, or you may use the shorter method applying the square brackets around the Nobel Gas which indicates the complete inner filled electrons in the core (or Kernal).

 

i.e:  [Ar] represents  1s2 2s2 2p6 3s2 3p6 or the 18 electrons in the Argon core.

 

* In columns VIB and IB, you may have to apply the d4/9 Rule (Never 4/9 total d orbital electrons in any spectroscopic notation except Nb 41; W 74; and Pt 78)
