### Educational Content on Identifying Radioactive Isotopes

#### Question
Pick the radioactive isotope in each set.

#### Options for Set (a)
- \( {}^{237}_{93}\text{Np} \)
- \( {}^{20}_{10}\text{Ne} \)

#### Answer
- The correct choice is \( {}^{237}_{93}\text{Np} \).

#### Explanation
Select an explanation for choosing the radioactive isotope:

- ○ Its atomic number is greater than 83.
- ○ Its atomic number is less than 83.
- ● It has more neutrons than protons in the nucleus.
- ○ It has fewer neutrons than protons in the nucleus.
- ○ It is an even-even nuclide.
- ○ It is an odd-odd nuclide.
- ○ none of these

A red cross indicates the selected explanation is incorrect.

#### Notes:
- **Isotopes**: Variants of elements with differing numbers of neutrons.
- **Radioactivity**: Often correlated with higher atomic numbers or imbalanced neutron to proton ratios.
