Rubidium: the essentials. Rubidium can be liquid at ambient temperature, but only on a hot day given that its melting point is about 40Â°C. It is a soft, silvery-white metallic element of the alkali metals group (Group 1).It is one of the most most electropositive and alkaline elements.ubidium is far too reactive to be found as the free metal in nature. It is relatively rare, although it is the 16th most abundant element in the earth's crust. Rubidium is present in some minerals found in North America, South Africa, Russia, and Canada.
