How do electrons differ from protons and neutrons?

An atom is made up of three main subatomic particles: protons, neutrons, and electrons.

Together, protons and neutrons make up the mass of an atom. Protons are electrochemically positive in charge, while neutrons are electrochemically neutral. Both protons and neutrons are large particles that are densely packed into the atom's nucleus.

Electrons are found in electron clouds that surround the nucleus; their movement and properties allow for the bonding characteristics of each atom. Electrons are electrochemically negatively charged particles that move randomly around the nucleus. Compared to protons and neutrons, they have a relatively small mass.

Protons and neutrons are not elemental particles; electrons are.

If a particle is considered elemental, it does not consist of quarks.

I hope this was useful, educator.

Electrons are negatively charged particles that orbit the nucleus of an atom, whereas protons are positively charged particles found in the nucleus and neutrons are neutral particles also found in the nucleus. Additionally, electrons have much smaller mass compared to protons and neutrons.
