Q:

Electron configuration of cobalt 2+?

Answer

The s,p,d,f configuration for cobalt (Co) is 1s22s22p63s23p64s23d7, determined by the position of the element on the periodic table. The electron configuration for Cobalt at ground state would simply be Co: [Ar] 4s²3d⁷.

The electron configuration of Cobalt will end in d block as Cobalt is an inner transition metal. Cobalt is in the 7th column of the d block and therefore has 7 d electrons d7.
