Most Reactive Elements

Some metallic elements are more likely to react than others.  These elements have a higher reactivity.

The family with the most reactive metals is called the alkali metals.  This group contains lithium, sodium, potassium, rubidium, cesium, and francium.  The metals become more reactive going down the periodic table of elements.

You will not find reactive metals in the ground in the elemental form.  They form compounds really easily.

The most reactive nonmetals are the halogen family.  This includes astatine, iodine, bromine, chlorine, and fluorine.  Going up, the nonmetals go from least reactive, to most reactive.
