Part 1. Express your answer as an isotope.

Part 2. Express your answer as an isotope.

 
The image displays a nuclear equation to solve, with a requirement to express the answer as an isotope. The equation is as follows:

\[ \text{____} \rightarrow \, ^{218}_{86}\text{Rn} + \, ^{4}_{2}\text{He} \]

Users are prompted to express their answer in an input box labeled "Express your answer as an isotope."

Below the input box, there is a checkbox labeled "A chemical reaction does not occur for this question."

Additional options include a "Submit" button for submitting the answer and a "Request Answer" button for assistance.

This setup is typically used for educational purposes in learning environments to test knowledge on nuclear reactions and isotopic expressions.

**Nuclear Equation Completion Task**:

The problem involves completing a nuclear equation for the decay of radon, represented as:

\[ \text{Radon-218} \rightarrow \, \_\_ \, + \, \text{Helium-4} \]

**Instructions**:

- Express your answer as an isotope.

**Equation Overview**:

The equation begins with an isotope of radon (Rn) with a mass number of 218 and an atomic number of 86. It decays to produce an unknown product and an alpha particle, which is a helium-4 (\( \text{He} \)) nucleus with a mass number of 4 and an atomic number of 2.

**Input Section**:

- A text input box is provided for you to enter the missing isotope that completes the equation.
- An option is present stating “A chemical reaction does not occur for this question,” meant to clarify that the process involves nuclear decay rather than a chemical reaction.

**Submission**:

- After entering your answer, click “Submit” to check your response.
- If unsure, you can also select “Request Answer” for additional assistance.

**Additional Details**:

In alpha decay, the parent nucleus loses two protons and two neutrons, forming a new element with atomic and mass numbers reduced by 2 and 4, respectively.
