Question

Pick the radioactive isotope and reasoning for each set

The image consists of a multiple-choice question about the properties of isotopes. **Question Part (b):** Isotopes Presented: - Option 1: \( \frac{227}{89} \text{Ac} \) - Option 2: \( \frac{28}{14} \text{Si} \) A radio button is selected for: - \( \frac{28}{14} \text{Si} \) **Explanation of Choice:** Below the isotopes, there is a section titled "Explain your choice" with several options. The selected option is: - "It has more neutrons than protons in the nucleus." Other Options Provided: - Its atomic number is greater than 83. - Its atomic number is less than 83. - 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 mark appears next to both the selected isotope and the selected explanation option, indicating incorrect selections.

### Educational Example on Isotopes #### Question: Given the isotopes of phosphorus: - \( \text{}_{15}^{29}\text{P} \) - \( \text{}_{15}^{31}\text{P} \) Select the correct isotope and explain your choice. #### Options: - \( \text{}_{15}^{29}\text{P} \) - \( \text{}_{15}^{31}\text{P} \) (Correct) #### Explanation of Choice: **Explain your choice:** - ○ Its atomic number is greater than 83. - ○ Its atomic number is less than 83. - ● It has more neutrons than protons in the nucleus. (Correct) - ○ It has fewer neutrons than protons in the nucleus. - ○ It is an even-even nuclide. - ○ It is an odd-odd nuclide. - ○ None of these. In this exercise, the correct isotope selected is \( \text{}_{15}^{31}\text{P} \), which has more neutrons than protons. This is demonstrated by selecting it in the interface, receiving a checkmark for the correct selection, but then indicating an explanation error due to an incorrect choice selection reasoning below.
