Question

How are isotopes defined?forms of different elements that have the same number of neutrons in each atomforms of different elements that have the same number of protons in each atomforms of the same element that differ in the number of neutrons in each atomforms of the same element that differ in the number of protons in each atom?

Answer 1

Your answer is C forms of the same element that differ in the number of neutrons in each atom because if the number of neutrons change the whole element changes.

Answer 2

Answer: Option (c) is the correct answer.

Explanation:

When there are same number of protons but different number of neutrons in the nuclei of two or more forms of an atom then they are known as isotopes.

For example, $^{12}_{6}C$ and $^{13}_{6}C$ are isotopes.

Thus, we can conclude that out of the following options, isotopes are defined as forms of the same element that differ in the number of neutrons in each atom.
