Detailed explanation-1: -Therefore, an atom that loses electrons becomes a positively-charged ion called a cation.

Detailed explanation-2: -So if it loses an electron, it contains one proton in excess w.r.t the electrons. Hence if an atom loses an electron, it acquires a net positive charge.

Detailed explanation-3: -Atoms can gain or lose electrons to become ions. When an atom loses an electron it gains a positive charge and is called a cation. When an atom gains an electron it gains a negative charge and is called an anion.
