Problem: Radon-222 decays to a stable nucleus by a series of three alpha emissions and two beta emissions.What is the stable nucleus that is formed?

FREE Expert Solution

We are asked to determine a stable nucleus that is formed when radon-222 undergoes a series of three alpha emissions and two beta emissions.

For this item, we need to follow the steps below:

  • Step 1. Write the chemical reaction for the series of emissions.
  • Step 2. Calculate the mass number, Z, and the atomic number, A, for the resulting nuclei.
  • Step 3. Find the stable nuclei in the periodic table based on the atomic number and mass number.
