Atom having configuration = 2K 8L 3M
Electronic configuration = 1s2 2s2 2px2 2py2 2pz2 3s2 3px1

K-shell has 1s-subshell
L-shell has 2s and 2p-subshell
M-shell has 3s and 3p-subshell

​Hence, total number of subshells = 5 (which are 1s, 2s, 2p, 3s and 3p)

Number of orbitals:
For 1s = 1 orbital
For 2s = 1 orbital
For 2p = 3 orbitals (2px 2py 2pz)
For 3s = 1 orbital
For 3p = 1 orbital (3px)

Total number of orbitals = 7

Number of s-orbital electrons = 6 (2 electrons each from 1s, 2s and 3s)

Number of unpaired electrons = 1 (in 3px-orbital)
