Answer 1

Answer:

A fundamental particle is a particle which cannot be broken down further. An atom is not a fundamental particle because it can be broken into electrons, protons and neutrons. An electron is a fundamental particle because it cannot be broken down further.Atoms are made up of protons, neutrons, and electrons. These classical subatomic particles consist of fundamental or elementary particles of matter. Since they are also particles of matter, they have size and mass. Fundamental particles are grouped as leptons and quarks.
