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 of an element share the same number of protons but have different numbers of neutrons. Let’s use carbon as an example. There are three isotopes of carbon found in nature – carbon-12, carbon-13, and carbon-14. All three have six protons, but their neutron numbers-6, 7, and 8, respectively-all differ.
Detailed explanation-3: -The number of neutrons can be different, even in atoms of the same element. Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes.
