Caesium

Caesium is obtained from..............

Effects/Uses
Caesium is used mainly in generators as an energy converter. Not commonly used elsewhere due to high reactivity with water.

Compounds/Mixtures
Caesium+Cadmium +Bromide = Can be used to create an active laser medium - CsCdBr3

Caesium+Carbonate = Compound used in energy conversion - Cs2CO3 -  See also Fuel Cell Generator 

Caesium+Hydrogen +Oxide = Highly corrosive - CsOH

Caesium+Water  =  Very reactive water compound. Spontaneously ignites with air - CsH2O
