Subshells

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

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
