Detailed explanation-1: -Hence, the particle which revolves around the nucleus of an atom is called an electron.
Detailed explanation-2: -Protons and Neutrons are part of the nucleus. Electrons are not a part of the nucleus and they revolve around it in fixed paths known as orbits.
Detailed explanation-3: -Electrons revolve around the nucleus in fixed orbits or shells called energy levels. Electrons rotate around the nucleus in one or more energy levels. These are represented as 1, 2, 3 i.e. an integer ‘n’ or as K, L, M, Suggest Corrections.
Detailed explanation-4: -An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom–the other two are protons and neutrons. Together, electrons, protons and neutrons form an atom’s nucleus.
