match each of the unknown ions to its appropriate description.

a− a) a nonmetal that gained one electron
b+ b) a metal that lost one electron
c2− c) a metal that lost two electrons
d2+ d) a nonmetal that gained two electrons

Metal -  form   a positively   charged ion   by  losing   valence electrons ( electron in the outermost energy level). For  example Metal D  loses 2  electrons to form D2+ ion. Non metal  form   a negatively  charged ion by  gaining one or  more electrons  in  order  to fill it's   valence   shell . For  example  non metal A gain 1 electron  to  form  A-  ion.
