#rubidium
Rubidium is not necessary for any forms of life as we know it. Safety precautions must be taken when handling the element though, for it reacts violently with water and can replace potassium in the body.
Discovered by Robert Bunsen and Gustav Kirchhoff in 1861 through the use of a spectroscope, rubidium’s name comes from the Latin word rubidus, meaning dark red because of its bright red emission spectrum.
Rubidium is the thirty seventh element on the periodic table, giving it thirty seven protons and electrons. It is the twenty third most abundant element in the Earth’s crust, but, because of its high reactivity, does not occur naturally in its free state.
On the periodic table, it falls into the group of alkali metals, the left most column, or group. The alkali metals are typically soft, shiny, and reactive metals that easily loose their one valence electron, turning into a cation with a +1 charge.
Rubidium is one of twenty six monoisotopic elements, though it does have a second (unstable) isotope (with a half-life of 49 billion years). The element itself is a soft silvery-white metal that oxidizes rapidly in the air and has been known to ignite spontaneously.
