Which describes a step in the process of forming an ionic bond? A metal atom loses electrons and becomes a positive ion. A metal atom gains electrons and becomes a negative ion. A nonmetal atom loses electrons and becomes a negative ion. A nonmetal atom gains electrons and becomes a positive ion.

Option (A) . A metal atom loses electrons and becomes a positive ion.

Explanation:

Ionic bond is a chemical bond in which electron is completely transferred from one atom to another. In ionic bond, one atom losses its outermost electron and forms positively charged ion called cation and other atom accept the outermost electron and becomes negatively charged ion called anion.
