Rubidium (RB) is a silvery white light metal. Soft and waxy, it is more chemical property than potassium.

It is easy to release electrons under the action of light. It reacts violently with water, creating hydrogen and rubidium hydroxide gas. Easily reacts with oxygen to form complex oxides. The hydrogen is readily ignited by the reaction with water, which gives off a great deal of heat. Pure metallic rubidium is usually stored in sealed glass ampoules. Rubidium is widely used in energy, electronics, special glass, medicine and other fields.
