Although the distilled rubidium was pyrophoric, they were able to determine the density and the melting point.The quality of this research in the 1860s can be appraised by the fact that their determined density differs by less than 0.1 g/cm Rb, is one of the most commonly used atomic species employed for laser cooling and Bose–Einstein condensation.

During magma crystallization, rubidium is concentrated together with its heavier analogue caesium in the liquid phase and crystallizes last.

Rubidium is not a known nutrient for any living organisms.

However, rubidium ions have the same charge as potassium ions and are actively taken up and treated by animal cells in similar ways.

Zone pegmatite ore bodies containing mineable quantities of caesium as pollucite or the lithium minerals lepidolite are also a source for rubidium as a by-product.

Both of those deposits are also sources of caesium.
