Which subatomic particle has a negative charge?

Proton
Neutron
Electron
Atom

The correct answer is: Electron

Electrons are subatomic particles that possess a negative charge. Protons and neutrons are located in the nucleus of an atom and have a positive and neutral charge, respectively. Atoms are made up of all three subatomic particles, but do not have a charge because the number of protons (positive) is equal to the number of electrons (negative). Therefore, they cancel each other out. Therefore, the electron is the only subatomic particle listed that has a negative charge.
