Co2+ Electron Configuration

What is the electronic configuration of Co2 + ion? ? 3

1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 7 Co E configuration is

2+ means 2 electrons are removed ... Since 4s 2 (not 3d s) is the outermost s, these electrons are removed

The configuration of Co2 + e is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 7 :)
