The statement that is true about the subatomic particle is

$\boxed{{\text{Electrons are the subatomic particles with the smallest mass}}}$

Further explanation:

Atom is the building unit of matter and is the smallest particle that an element can possess. The central part of an atom is called atomic nucleus. There are three subatomic particles, namely protons, electrons and neutrons in an atom. Out of these three, protons and neutrons reside in the nucleus of the atom while electrons revolve around the atomic nucleus in definite orbits.

Proton is the subatomic particle that carries a positive charge, electrons are negatively charged and neutrons are neutral with no charge on them.

Protons are the only subatomic particles to have charge.

Only neutrons have no charge whereas both protons and electrons are charged subatomic particles. Therefore this statement is false.

Electrons are the subatomic particles with the smallest mass.

The mass of an electron is $9.1 \times {10^{ - 31}}{\text{ kga}}$ , that of protons is $1.6726219 \times {10^{ - 27}}{\text{ kg}}$ and that of neutrons is $1.674927471 \times {10^{ - 27}}{\text{ kg}}$ . So the mass of electrons is the smallest among all the subatomic particles. Therefore this statement is true.

Neutrons orbit the nucleus of the atom.

Neutrons and protons are located inside the nucleus of an atom while electrons revolve around it in definite orbits. Therefore this statement is false.

Subatomic particles all have the same mass.

The mass of an electron is $9.1 \times {10^{ - 31}}{\text{ kg}}$ , that of protons is $1.6726219 \times {10^{ - 27}}{\text{ kg}}$ and that of neutrons is $1.674927471 \times {10^{ - 27}}{\text{ kg}}$ . The mass of protons and neutrons is almost same but that of electrons is quite different from masses of the other two particles. Therefore this statement is false.
