Which Elements Have a Half Filled P Subshell?

All the elements belong to group 15 have half-filled p subshell. Thus, N, P, As, Sb, Bi and Mc all these elements belongs to 15 group, has half-filled p subshell. Among these elements, nitrogen has the lowest atomic mass and is therefore considered as the lightest element.

Which elements have a partially filled p subshell?

Halogens are in p block. They have partially filled p sublevel.

What is a half filled p subshell?

The p orbitals are half-filled; there are three electrons and three p orbitals. This is because the three electrons in the 2p subshell will fill all the empty orbitals first before pairing with electrons in them.
