  • Sodium 1s2 2s2 2p6 3s1

    Iron 1s2 2s2 2p6 3s2 3p6 3d6 4s2

    I can’t give colbalt as it doesn’t exist .. did you mean cobalt?

    Cobalt 1s2 2s2 2p6 3s2 3p6 3d7 4s2 or [Ar] 3d7 4s2

    I must say that whoever teaches computer studies or information studies ought to be dismissed for incompetence immediately if they haven’t taught you to do simple web searches of how do do this!

    So here’s how to do the last one:
