Question
Chapter 20, Problem 78AP
Interpretation Introduction
Interpretation:
Theradioactivity of tritium is to be discussed.
Concept introduction:
Natural decay is a process in which the atomic nucleusis unstable and releases energy through the emission of radiations such asalpha particles. It is also known as radioactive decay. The material that exhibits these properties is said to be radioactive.
