    Hence Mg has 10 core electrons and 2 valence electrons. The number of core electrons depends on the period (row) in which the element is found.

    10

    Explanation:

    Mg is element No. 12.

    It has 12 electrons, with a shell configuration of 2, 8, 2.

    The last two electrons are the valence electrons; the remaining 10 electrons are the inner or core electrons.
