Which statements about subatomic particles are false? (select all that apply.) protons and electrons have charges of the same magnitude but opposite sign. protons have about the same mass as neutrons. some atoms don't have any protons. protons and neutrons have charges of the same magnitude but opposite signs?

Subatomic particles are those particles which are smaller than the atom such as electrons, protons and neutrons.

Protons are positively charged particle whereas electrons are negatively charged particle with same magnitude.

Neutrons have about the similar mass as protons but without any electric charge (neutral).

The false statement for the subatomic particles are that some atoms don't have protons: All atoms contains three subatomic particles. Every atom must have protons otherwise atom doesn't exist.

The another false statement for the subatomic particles that the protons (positively charge) and neutrons (neutral) have charges of the same magnitude.
