Radioactive tracers are substances that contain a radioactive atom to allow easier detection and measurement.

(Radioactivity is the property possessed by some elements of spontaneously emitting energy in the form of particles or waves by disintegration of their atomic nuclei.) For example, it is possible to make a molecule of water in which one of the two hydrogen atoms is a radioactive tritium (hydrogen-3) atom.

Symbol- Each element is assigned a chemical symbol.

This symbol usually originates from its name or its Latin name. Each element's symbol is composed of a capital letter followed by one or two lowercase letters. This atomic number is equal to the number of protons in the nucleus of that particular atom.

(See sidebar on Davy in the calcium entry in Volume 1.) There are very few uses for potassium as a pure element.

The main difference between the tracer molecule containing tritium and the normal molecule is that the tracer molecule continually gives off radiation that can be detected with a Geiger counter or some other type of radiation detection instrument. The alkali metals are the elements that make up Group 1 (IA) of the periodic table.The periodic table is a chart that shows how chemical elements are related to one another.For example, the element cobalt (Co) has an atomic number of 27.This atomic number is also the number of protons in the atom. Mass- The mass of an atom, expressed in atomic mass units (AMU), is roughly equal to the number of protons plus the number of neutrons.

For example, a number of different oil companies may take turns using the same pipeline to ship their products from the oil fields to their refineries.
