Rubidium
allotrope
Rb
A soft, silvery alkali metal that ignites spontaneously in air
← Allotrope of Rubidium
So reactive it bursts into flame on contact with air — rubidium's simple cubic structure belies its explosive personality.
A crystalline allotrope of Rubidium (space group Im-3m), sourced from the Crystallography Open Database (COD 9008549).
