The electron configuration of copper(II) is [Ar] 3d9 .
Copper is [Ar] 3d10 4s1
The electron configuration of Cu2+ is [Ar]3d94s0.
Cobalt(II) electron configuration is [Ar]3d7.
The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
neon
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
The Fe2 plus electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6.
The electron configuration of Cu2+ is [Ar]3d94s0.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
Cobalt(II) electron configuration is [Ar]3d7.
The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
