Question

Why are electrons, protons and neutrons called fundamental particles?


​

Answer 1

Answer:

Today, scientists think that electrons truly are fundamental particles that cannot be broken down into smaller, simpler particles. ... Protons and neutrons, on the other hand, are no longer thought to be fundamental particles. Instead, they are now thought to consist of smaller, simpler particles of matter called quarks.

Answer 2

According to new discoveries, protons and neutrons are not fundamental particles because they are made up of smaller particles known as quarks. Whereas, electrons are made up of another fundamental particles known as leptons. Earlier, scientist used to believe that electrons protons and neutrons make up the matter and that's why they were known as fundamental particles.
