CHEM120 OL, Week 6 Lab


OL Lab 10: Nuclear Chemistry
Objectives:
 Identify the differences between chemical reactions and nuclear reactions.
 Identify the concept of radioactive decay.
 Identify the nuclear changes associated with alpha, beta or gamma decay.
 Write the products of nuclear reactions involving alpha, beta or gamma
emissions.
 Explain the concept of half-lives and complete half-life calculations.
Not all atoms are stable. When atoms are born in a nuclear reactor, whether it be the
heart of a star or a power plant, a portion of them are radioactive and are referred to as
radioisotopes. Theseradioisotopes break down over time, releasing energy and
transforming into more stable forms in processes known as radioactive decay.
Depending upon the specific radioisotope, this process can be near instantaneous or
take trillions of years.

In this lab, you will explore radioactive decay as you learn about various types of
radioactivity and half-life.
