Question

The elements ${}^{30}S{i}_{14}{,}^{31}{P}_{15}$ and ${}^{32}{S}_{16}$ are called :

• A. isotones
• B. isobars
• C. isotopes
• D. mirror nuclei

Answer 1

The correct option is A isotones

The elements ${}^{30}S{i}_{14}{,}^{31}{P}_{15},an{d}^{32}{S}_{16}$ are called Isotones, because they have different atomic numbers and different atomic masses but same no.of Neutrons are present.

So answer is A.
