    Almost right! Electrons are negatively charged so they will make an atom more negative. What the atom's charge becomes depends on what it was to begin with.

    For example is a Magnesium ion Mg+2 gains one electron it is still positive Mg+1 as the electron was not enough on its own to make it negative.
