match of the unkwown ions to its appropriate description is as below
A-A)= A non metal that gained one electron.
B+B) = A metal that lost one electron
C2-C) = A non ,metal that gained two electrons
D2+D)= A metal that lost two electrons.
Explanation
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.
