Detailed explanation-1: -The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Detailed explanation-2: -The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom. This is known as the atomic number, Z. The removal or addition of electrons to a neutral atom creates ions that have a net negative or positive charge.

Detailed explanation-3: -Atomic number of an element tells about the number of protons present. The number of protons present will be equal to the number of electrons. Therefore, the atomic number of an atom is equal to both the number of electrons and protons present in an atom.

Detailed explanation-4: -atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

Detailed explanation-5: -The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.
