    Because the atom would normally be neutral. But it loses 2 electrons so it becomes positively charged by 2x their individual charge.

    It would never be 12 - doesn't even have that many protons/electrons.
    There are 6 protons, and 4 electrons.

    6 protons, 4 electrons so net charge is +2

    Overall charge = positive charge - negative charge
    There's now 2 more protons than electrons, meaning the overall charge is +2e.
