Kathleen · Answer 1

a structural variation in which different atoms of the same element have different numbers of neutrons

Explanation:

An isotope is an atom of an element having the same number of protons but different number of neutrons. Different isotopes are used for different purposes. Example: some are used in medicines, food irradiation, etc.

Carbon has three isotopes C 12, C 13, C 14. All three of them have 6 protons but have different numbers of neutrons.

C 12 is a common element and is abundant in nature

C 13 is less abundant than C 12

C 14 is used for dating fossils. It is radioactive
