<h2>Answer:</h2><h3>Term:</h3>

A- : A nonmetal that gained one electron.

B+: A metal that lost one electron.
C-2: A nonmetal that gained two electron.
D+2: A metal that lost two electrons.

Explanation:

A metal is an atom which is present in the first and second column of periodic table and have ability to lose electron.

So any cation which is formed by losing one electron will have positive sign and will be metal.

So B+ and D+2 are metals and have lost 1 and 2 electrons respectively.

On the other hand, nonmetals have capability to gain electrons.

So A- and C-2 are nonmetals that have lost 1 and 2 electrons respectively.
