Which of the following statements is true about ions?

a.

Cations form when an atom gains electrons.

b.

Cations form when an atom loses electrons.

c.

Anions form when an atom gains protons.

d.

Anions form when an atom loses protons.

B. Cations form when an atom loses electrons.

Cations are the ions that a positively charged. And the way this is to happen is for the atom to lose electrons. Knowing that the atom is has equal number of electrons and protons, so it is neutral, and when it loses electrons, it becomes positively charged, because it has more of protons.
