Answer 2

Answer: The correct answer is isotopes.

Explanation:

Isotopes are defined as the chemical species of the same element which has different atomic mass but have same atomic number.

It can also be said that they have different number of neutrons but have same number of protons.

For Example:  $_6^{12}\textrm{C}\text{ and }_6^{14}\textrm{C}$ are the isotopes of carbon. They have 6 and 8 number of neutrons respectively.

Hence, different isotopes of an element will have different number of neutrons.
