Detailed explanation-1: -Isotopes are known as the atoms of the same element having the same atomic number i.e same number of protons, but different atomic mass numbers i.e different numbers of neutrons. Example: The Carbon isotopes are given as : 6 C 11, 6 C 12, 6 C 13, 6 C 14 .
Detailed explanation-2: -Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
Detailed explanation-3: -Atoms having same atomic number and different mass numbers are known as isotopes.
Detailed explanation-4: -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.
