Explanation:
Detailed explanation-1: -Composition of the Atom. The atom consists of a tiny nucleus surrounded by moving electrons. The nucleus contains protons, which have a positive charge equal in magnitude to the electron’s negative charge. The nucleus may also contain neutrons, which have virtually the same mass but no charge.
Detailed explanation-2: -Atomic nuclei consist of protons and neutrons. The number of protons is the atomic number (Z), and the sum of the number of protons (Z) and neutrons (N) is the mass number (A). The particles composing the nuclei are called “nucleons.”
Detailed explanation-3: -The nucleus of the atom consists of protons and neutrons.
