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.
