Question

The nuclei ${}_8{\text{O}}^{16},{}_8{\text{O}}^{17}$ and ${}_8{\text{O}}^{18}$ can be described as

• A. Isotones
• B. Isobars
• C. Isotopes
• D. Isomers

Answer 1

The correct option is C Isotopes

The nuclei having same atomic number $\left(Z\right)$ but different mass number $\left(A\right)$ are called isotopes.

Here, all the three nuclei have same atomic number $(Z=8)$ and different mass number.

Hence, option $\left(C\right)$ is correct.
