Here's what I get.
Explanation:
You can readily compare the following with the ones you see from http://ptable.com/ (by clicking the "Orbitals" tab):
(a) Valence electron configuration
#"Sc": "4s"^2"3d"^1# #"Y":color(white)(l) "5s"^2"4d"^1# #"La": "6s"^2"5d"^1# #"Ce": "6s"^2"4f"^1"5d"^1# #"Gd": "6s"^2"4f"^7"5d"^1# #"Lu": "6s"^2"4f"^14"5d"^1# #"Ac": "7s"^2"6d"^1# #"Pa": "7s"^2"5f"^2"6d"^1# #"U": color(white)(l)"7s"^2"5f"^3"6d"^1# #"Np": "7s"^2"5f"^4"6d"^1# #"Cm": "7s"^2"5f"^7"6d"^1#
(b) Valence electron configuration
The pnictogens:
#"N"color(white)(l): "2s"^2"2p"^3# #"P"color(white)(l): "3s"^2"3p"^3# #"As": "4s"^2"3d"^10"4p"^3# #"Sb": "5s"^2"4d"^10"5p"^3# #"Bi": "6s"^2"4f"^14"5d"^10"6p"^3# #"Mc": "7s"^2"5f"^14"6d"^10"7p"^3#
(c) Valence electron configuration
The noble gases:
#"Ne": "2s"^2"2p"^6# #"Ar": "3s"^2"3p"^6# #"Kr": "4s"^2"3d"^10"4p"^6# #"Xe": "5s"^2"4d"^10"5p"^6# #"Rn": "6s"^2"4f"^14"5d"^10"6p"^6# #"Og": "7s"^2"5f"^14"6d"^10"7p"^6#
