Which statements is true of all atoms that are anions?
a. the atom has more electrons than protons.
b. the atom has more protons than electrons.
c. the atom has fewer protons than does a neutral atom of the same element.
d. the atom has more neutrons than protons.

The atom has more electrons than protons.

Explanation:

Ions may be defined as the element that contains either positive or negative charge over it. Two types of ions are cations and the anions. The charge on the species is obtained by the loss or gain of electron.

Anions carry negative charge over them. Negative charge occurs by gaining of the electrons from its neighboring atoms. The number of protons and electrons are equal in neutral atom. Since, the ions gain the electron and hence it carries more protons.

Thus, the correct answer is option (a).
