Nuclear Reactions

Nuclear reactions are processes in which the fundamental characteristics of a nucleus changes. They change into a completely different nucleus. These processes occur naturally in an unstable nucleus. Bombarding an energetic particle can induce nuclear reactions. In this article, both the naturally occurring nuclear reactions are termed as radioactive decay and the induced nuclear reactions are further categorized as nuclear fission and nuclear fusion.

It is handy to have an equation to quickly determine the number of atoms left in a radioactive sample as a function of time. For this we can divide the initial amount by two for every half-life of time, the following equation does exactly that: No No 2 1/2 (21/2) where Nois the initial number of atoms at t=0, t is time passed and is the half-life. Use the above equation to help you answer the question below. Substance X has a half-life of 10 years, if you start with 1000 grams, how much will be left after 100 years?
