Rubidium is an extremely reactive metalit ignites spontaneously in the presence of air and decomposes water explosively, igniting the liberated hydrogen. Because of its reactivity, the metal and several of its compounds are hazardous materials, and must be stored and .
Europium Element information, properties and uses ...
Europium's story is part of the complex history of the rare earths, aka lanthanoids. It began with cerium which was discovered in 1803. In 1839 Carl Mosander separated two other elements from it: lanthanum and one he called didymium which turned out to be a mixture of two rare earths, praseodymium and neodymium, as revealed by Karl Auer in 1879.

A process suitable for producing curie quantities of quite pure Sr82,85 is given. After a Mo target is irradiated with energetic protons having energies greater than about 200 MeV, thus producing a large number of radioactive species, the particular species of Sr82,85 are substantially separated from the other products by a 6step process.
WebElements Periodic Table » Rubidium » the essentials
Rubidium: the essentials. It is a soft, silverywhite metallic element of the alkali metals group (Group 1). It is one of the most most electropositive and alkaline elements. It ignites spontaneously in air and reacts violently with water, setting fire to the liberated hydrogen. As so with all the other alkali metals, it forms amalgams with mercury.
