Valence Electron Configurations for Main Group Elements The valence electron configurations for the main group elements are given on the periodic table below. Note that except for He the number of valence electrons is equal to the group number. elements in the same group have the same valence electron configuration, when the period number is replace by the symbol n 1A 8A 1 H 1s 1 2A 3A 4A 5A 6A 7A He 1s 2 2 Li 2s 1 Be 2s 2 B 2s 2 2p 1 C 2s 2 2p 2 N 2s 2 2p 3 O 2s 2 2p 4 F 2s 2 2p 5 Ne 2s 2 2p 6 3 Na 3s 1 Mg 3s 2 3B 4B 5B 6B 7B 8B 1B 2B Al 3s 2 3p 1 Si 3s 2 3p 2 P 3s 2 3p 3 S 3s 2 3p 4 Cl 3s 2 3p 5 Ar 3s 2 3p 6 4 K
