Order of subshells
1s,2s, 2p,3s, 3p, 4s, 3d, 4p
Group 1 elements have what valence subshell
s
Group 2 elements have what valence subshell
s
Group 3 and 8 elements have what valence subshell
p
Transition metal valence subshell
d
Hunds Rule states
within a subshell, electrons will individually occupy each orbital before any orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
Less stable elements spectra general colour
Blue - travel further
More stable elements spectra general colour
Red - travel less
