Electron configuration Navigate by clicking the element on the table above or using the table Cu Ce Co Cs none of the above Cs is a main-group element.

Cr3+ has 3 electrons removed from the outermost shell. Therefore, the electronic configuration comes out to be [Ar]3d3. 2020-04-02 · The electron configuration for cobalt is 1s2 2s2 2p6 3s2 3p6 3d7 4s2. The first number in each group identifies the energy level of the electrons. The letter represents the type of shell in which the electrons sit, while the final number denotes the number of electrons in the shell.
