Subshells edit

Subshell label ℓ Max electrons Shells containing it Historical name
s 0 2 Every shell  sharp
p 1 6 2nd shell and higher  principal
d 2 10 3rd shell and higher  diffuse
f 3 14 4th shell and higher  fundamental
g 4 18 5th shell and higher (theoretically) (next in alphabet after f)
h 5 22 6th shell and higher (theoretically) (next in alphabet after g)
i 6 26 7th shell and higher (theoretically) (next in alphabet after h)
j 7 32 8th shell and higher (theoretically) (next in alphabet after i)

Number of electrons in each shell edit

 
Shells and subshells. The number of filled cells is the number of electrons at the level. Red color indicates sublevel s; orange - p; yellow - d; green - f; blue - g; indigo - h; violet - i
