Yes, electrons are indeed subatomic particles. Subatomic particles are particles that are smaller than atoms, which are the basic units of matter. Electrons are one of the three fundamental particles that make up atoms, alongside protons and neutrons. Electrons carry a negative electrical charge and have a much smaller mass compared to protons and neutrons. They orbit around the nucleus of an atom in specific energy levels or electron shells, determining the chemical and physical properties of the atom. Electrons are crucial for the formation of chemical bonds and the behavior of matter at the atomic and molecular levels.
