Detailed explanation-1: -The centre of the atom is called the nucleus. It consists of protons and neutrons. Electron is a negatively charged species that revolves around the nucleus in fixed orbits . Proton is a positively charged specie and neutron has no charge. Proton and neutrons are located inside the nucleus.
Detailed explanation-2: -The nucleus (or center) of an atom is made up of protons and neutrons. The number of protons in the nucleus, known as the “atomic number, ” primarily determines where that atom fits on the Periodic Table.
Detailed explanation-3: -The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge).
Detailed explanation-4: -Protons and neutrons are found in the nucleus at the center of atom. Because these particles are so similar and because they are the particles out of which are made, protons and neutrons are often collectively called “nucleons".
Detailed explanation-5: -The nucleus is primarily composed of protons and neutrons, collectively called nucleons.
