    2 electrons

    E. neon

    Explanation:

    Metals lose electrons under certain conditions to attain a noble gas electron configuration. Magnesium has 12 electrons and its electron configuration is

    1s² 2s² 2p6⁶ 3s²

    When magnesium loses 2 electrons, it acquires the electron configuration of neon (10 electrons).
