In this lesson, we will learn how to determine the products of radioactive decay chains and identify the type of radioactive decay from the decay products.

Q1:

Astatine-218 undergoes beta decay to Radon-218. Radon-218 undergoes alpha decay to polonium-214. This is shown in the following nuclear equation.

What is the value of 𝑟 in the equation?

What is the value of 𝑠 in the equation?

Q2:

Which type of nuclear radiation has no mass?

Q3:

The diagram shows a beryllium-11 nucleus undergoing two-step radioactive decay. Red circles represent protons, gray circles represent neutrons, and blue circles represent electrons. What isotope is produced through this reaction?
