Atomic structure

Atomic radius/A: 2.98 atomic volume/cm3 / mol: 55.9 covalent radius/A: 2.16

Electronic configuration: 1 2 3 4 s2p6 s2 s2p6d10 s2p6 5 s1 ion radius/A: 1.52 oxidation state: 1

Discovery

In 1861, by R.W. Bunsen and g. Kirchoff (Germany, HaiDeEr fort university) found.

Source

Is very rich, but more dispersed, production is restricted, generally by the production of lithium produces in the process.

Element USES

Used as catalyst, test, etc.
