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.

Detailed explanation-2: -the number of protons in all the atoms of a particular element is same, therefore to have different mass numbers, isotopes contain different number of neutrons. Q.

Detailed explanation-3: -Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.

Detailed explanation-4: -More About Isobars It will have the same number of nucleons. The number of protons and neutrons alone will vary but the number of nucleons or the sum of protons and neutrons in isobars will always be same. Isobars always have different atomic structure because of the difference in atomic numbers.

Detailed explanation-5: -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.
