Question
**Counting Valence Electrons in an Atomic Ion**

**Question:**
How many valence electrons are in \( \text{Rn}^{2+} \)?

**Answer Input Section:**
- There is a text box provided where the user can enter their answer.
- Accompanying the text box are two additional buttons: a cross symbol (X) likely used for clearing the input, and a circular arrow symbol (↻) likely used for resetting or refreshing the section.

**Explanation and Interaction Buttons:**
- Below the answer input section, there are two buttons: "Explanation" and "Check".
  - **Explanation**: This button might provide a detailed description or guidance on how to determine the number of valence electrons for the given ion.
  - **Check**: This button is probably used to submit the user's answer in order to verify its correctness or get feedback.

**Additional Context:**
- The question pertains to the element radon (Rn) in a specific ionic state (\(2+\)). Understanding the normal electron configuration of radon and how it changes when it loses two electrons is key to solving this problem.

This interactive exercise aids students in practicing how to count valence electrons in ions, an essential skill in understanding chemical bonding and properties.
