Detailed explanation-1: -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-2: -Atomic number, atomic mass, and relative atomic mass Forms of the same atom that differ only in their number of neutrons are called isotopes. Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons.
Detailed explanation-3: -Isotopes are defined as the atoms of the same element, having the same atomic number but different mass numbers.
Detailed explanation-4: -Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table.
