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: 21885218–214–AtRn+Po++𝛽𝛽𝛼
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?
