Detailed explanation-1: -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-2: -The atomic number (Z) of an element is the number of protons in the nucleus of each atom of that element. This means that the number of protons is the characteristic which makes each element unique compared to all other elements.

Detailed explanation-3: -The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number (np) or the number of protons found in the nucleus of every atom of that element.

Detailed explanation-4: -atomic number is defined as the total number of protos present inside the nucleus of an atom. Atomic number is also known as proton number. It is represented as Z. Atomic number(Z)=Number of protons=Number of electrons.

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.
