The noble gases are sometimes called inert gases because Group 18 (VIIIA) elements react with very few other elements.
In fact, no compound of argon has ever been produced.
One application for the tracer molecule described above would be to monitor plant growth by watering plants with it.
The plants would take up the water and use it in leaves, roots, stems, flowers, and other parts in the same way it does with normal water.
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.
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.
Radioactive tracers are substances that contain a radioactive atom to allow easier detection and measurement.
