Answer 2

Answer:

a) Atoms of same element

Explanation:

Elements with the same atomic number but a different mass number are defined as “Isotopes”. The number of protons and neutrons combined together is called atomic mass or mass number of an element, whereas the total number of protons gives the atomic number of an element. In a certain element, the number of protons will always remain constant.

eg. Isotopic forms of Uranium- U-235, U-238
