Alkali Metals

3:41 Minuten

The element group one in the periodic table consists of the gas hydrogen and the element family of the six alkali metals: lithium, sodium, potassium, rubidium, caesium and francium. With only one single electron in their outer shell the alkali metals are very reactive. Because of this commonality, the elements behave similarly and form the group of alkali metals.

In this film some of the most important characteristics of alkali metals are illustrated by concise examples and experiments.
