Match each of the unknown ions to its appropriate description. match term definition a− a) a nonmetal that gained one electron b+ b) a metal that lost one electron c2− c) a nonmetal that gained two electrons d2+ d) a metal that lost two electrons

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.
