Detailed explanation-1: -Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Detailed explanation-2: -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-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: -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.

Detailed explanation-5: -Isotones are the atoms of different elements with same number of neutrons. Example: (6C13, 7N14) Isotones are the different elements that contain same number of neutrons.
