What are atomic number,nucleons,and mass number? Give the relation between them.
(N/A) Atomic Number $(Z)$: The number of protons present in the nucleus of an atom is called the atomic number.
Nucleons: Protons and neutrons present in the nucleus are collectively known as nucleons.
Mass Number $(A)$: The total number of protons and neutrons present in the nucleus is called the mass number.
Relation: $A = Z + N$,where $N$ is the number of neutrons.
Nucleons: Protons and neutrons present in the nucleus are collectively known as nucleons.
Mass Number $(A)$: The total number of protons and neutrons present in the nucleus is called the mass number.
Relation: $A = Z + N$,where $N$ is the number of neutrons.
