Problem: Which of the following is true in regard to a charged atom?A. The number of protons and the number of electrons within the same atom are unequal.B. When an atom gains an electron, it becomes a cation, which is positively charged.C. When an atom loses an electron, it becomes an anion, which is negatively charged.D. The magnitude of the negative charge is equal to the magnitude of the positive charge.

Ions form as a result of loss or gain of electrons from neutral atoms or molecules.

Cations are positively-charged ions and form by loss of electrons.

Anions are negatively-charged ions and form by gain of electrons.
