Lesson: Decay Chains

In this lesson, we will learn how to describe the four radioactive decay chains and identify the decay chain of an isotope from its nuclide symbol.

Worksheet: 14 Questions

Q1:

An atom of converts to via a sequence of 11 nuclear decays. The second, third, ninth, and tenth decays are decays and the others are decays. Which of the following nuclides is not formed in this decay pathway?

Q2:

An atom of converts to via a sequence of 7 nuclear decays. The second, fourth, and seventh decays are decays and the others are decays. Which of the following nuclides is not formed in this decay pathway?

Q3:

How many decays take place?
