    Please refer to the attached file. Cheers.

    1. 24Na: No matter which isotopes of Na you are looking at, sodium always has 11 protons because its atomic number is 11. It has 13 (24 - 11) neutrons. Because it has 11 protons, it also has 11 electrons.

    2. Al: 1s2 2s2 2p6 3s2 3p1

    F-: 1s2 2s2 2p6

    3. The electron configuration of Ar is [Ne] 3s2 3p6
    For ...
