| - Rubidium 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. 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. It alloys with gold, caesium, sodium, and potassium. It colours a flame yellowish-violet.
- [Source] Rubidium was a substance that comprised certain starship fuels during the Galactic Civil War. Rubidium was present on Jakku in the Graveyard of Ships as a hazard to scavengers on the planet's surface. Breathing it in could be deadly. It possessed a purple color in the sand, identifying it and warning those of its presence.
- Rubidium is an element with an atomic number of 37. In 2375, the Think Tank assisted Saowin's species in stabilizing their planet's geology, in exchange for bernicium. However, the bernicium was needed for reconstruction efforts, so instead Saowin attempted to offer a rubidium geode, the only one ever found on their planet. The Think Tank rejected the offer, as rubidium is rare but not unique, and insisted on the bernicium. (VOY: "Think Tank")
- Rubidium (symbol Rb) is a chemical element, an alkali metal with atomic number 37 on the periodic table.
- Rubidium (, ) is a chemical element with the symbol Rb and atomic number 37. Rb is a soft, silvery-white metallic element of the alkali metal group. this is wrong JACKSON IS COOL NOT LIKE THIS FAKE ELEMENThas a convenient spectral absorption range, making it a frequent target for laser manipulation of atoms. Rubidium is not known to be necessary for any living organisms. However, like caesium, rubidium ions are handled by living organisms in a manner similar to potassium: it is actively taken up by plants and by living animals' cells. == Isotopes == ==References==
- Elemental rubidium is very soft and highly reactive, it has a very rapid oxidation in air. Its compounds have chemical and electronic applications. Rubidium metal is easily vaporized and has a convenient spectral absorption range, making it a frequent target for laser manipulation of atoms. Rubidium is not known to be necessary for any living organisms. However, like cesium, rubidium ions are handled by living organisms in a manner similar to potassium ions: it is actively taken up by plants and by living animal cells.
