#### Activity of Metals - Purdue University

The most active metals are so reactive that they readily coine with the O 2 and H 2 O vapor in the atmosphere and are therefore stored under an inert liquid, such as mineral oil. These metals are found exclusively in Groups IA and IIA of the periodic table. Metals in the second class are slightly less active.

Potassium is one of the alkali metals. 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. The alkali metals also include lithium, sodium, rubidium, cesium, and francium. They are among the most active metals.
