Question

Why are electrons and protons fundamental particles of an atom? answer fast...

Answer 1

Explanation:

They are composite particles in that they are made of other particles (quarks), which are fundamental. The quarks are bound together by force carrying fundamental particles called gluons. These particles mediate the strong nuclear force. Electrons are fundamental particles in that they are not made of other particles

Answer 2

Answer:

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. But a proton and neutrons can be broken down further into 3 quarks. ... They are all made up of the fundamental particles.
