Question

Identify the pair of isotopes from the following: ₈X¹⁶ , ₇X¹⁶ , ₈X¹⁷

Answer 1

Isotopes are the variants of an element which have same atomic number but different atomic mass. Here ₈X ¹⁶ and ₈X ¹⁷ are isotopes as they posses same atomic numbers (i.e. 8), but different atomic mass (16 and 17).
