MCQ
Many atoms have non-integral atomic masses because
  • A
    they have isotopes
  • B
    their isotopes have non-integral masses
  • C
    their isotopes have different masses
  • ✓
    Both $A$ and $C$
✓

Answer

Correct option: D.
Both $A$ and $C$
d
Non integral atomic masses of elements are due to existence of isotopes of that element which have different masses. And these isotopes occur in nature in different proportion. Both $A$ and $C$
