Nucleons are composite particles made up of protons and neutrons. The protons and neutrons collectively present in the nucleus of an atom are called nucleons. The nucleons occupy very small space inside the nucleus. Nucleons are an important part of an atomic nucleus and therefore, they are important in particle physics.
Muons and tauons. Muons and tauons are heavier and highly unstable versions of the electron. Muons have mass 207 times larger than electrons and a lifetime of 2.20 microseconds. It can be created in cosmic rays at different heights above the earth.
