GENERAL KNOWLEDGE

Detailed explanation-1: -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. For example, carbon has six protons and is atomic number 6.

Detailed explanation-2: -Isotopes are atoms with the same number of protons, but differing numbers of neutrons .

Detailed explanation-3: -Isotopes are each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties.

Detailed explanation-4: -Nuclei with the same number of protons but a different number of neutrons are called isobars.

Detailed explanation-5: -Isotopes are atoms of the same element that have the same number of protons (i.e., atomic number, “Z") but a different number of neutrons, meaning that their mass number, “A", varies.
