It really depends what particle you are comparing it to. Compared with the neutron and proton:
The electron has a much smaller mass - roughly 2000 times smaller than the neutron or proton.
As far as we know, the electron is a truly elementary particle. Protons and neutrons are made up of smaller particles (the quarks).
The electron has a negative charge, the proton a positive charge, and the neutron is electrically neutral.
Because they are particles, and they are part of the atomic structure.
electrons
No. electrons are sub-atomic particles.
atomic nucleus
Protons are positive particles from the atomic nucleus; electrons are negative particles.
electrons
Electrons... Electrons are the atomic particles that have a negative electronic charge
electrons
Protons and neutrons are situated in the nucleus; electrons orbit this atomic nucleus.
The three main types of atomic particles are protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Protons and neutrons are found in the nucleus of an atom, while electrons orbit around the nucleus.
The energy is different.
