    Electron configuration of:

    Cr = 1s2 2s2 2p6 3s2 3p6 3d5 4s1

    Cr2 + = 1s2 2s2 2p6 3s2 3p6 3d4

    Cu = 1s2 2s2 2p6 3s2 3p6 3d10 4s1

    Cu2 + = 1s2 2s2 2p6 3s2 3p6 3d9

    Co = 1s2 2s2 2p6 3s2 3p6 3d7 4s2

    Co3 + = 1s2 2s2 2p6 3s2 3p6 3d6

    s can max contain 2 electrons.

    p can max contain 6 electrons.

    d can max contain 10 electrons.

    f can max contain 14 electrons.
