The Jefferson Lab indicates that rubidium is used for removing gases in vacuum tubes, making photocells, and making certain glasses. It may also find use in propelling spacecraft engines. The element is likely be used more often as it becomes better understood.Know More
The Jefferson Lab states that rubidium was initially discovered in 1861 by Robert Bunsen and Gustav Kirchoff while they were examining samples of the mineral lepidolite using a spectroscope. Upon looking at a sample, the two noticed some peculiar red lines. Bunsen then isolated samples of rubidium metal. In modern times, rubidium is obtained via refining lithium. Out of the compounds that rubidium can form, none are commercially useful. Common rubidium compounds include rubidium chloride, rubidium monoxide and rubidium copper sulphate. A combination of rubidium, silver and iodine is potentially useful in film batteries due to its electrical properties.
Lenntech states that rubidium, part of the alkali metal group, is soft and appears as silvery-white and metallic. Rubidium can become liquid during hot days and is known to act violently with water and ice. It's probably the 16th most common element within the earth's crust. Rubidium is considered to be similar to potassium in that it's not considered threatening by any environments. It exists in the minerals pollucite, carnallite, zinnwaldite and leucite. Very little rubidium is produced annually since there are few practical uses for it, but it's still used for research purposes. Rubidium is considered to be moderately toxic when ingested.Learn more in Chemistry
The formula for rubidium iodide, also written as rubidium(I) iodide, is RbI. Rb is the chemical symbol for rubidium, and I is the chemical symbol for iodine.Full Answer >
The noble gases, including radon, helium, argon, xenon, neon and krypton, are all monatomic. Since the noble gases are the only stable gases, they're always monatomic. However, if the temperature is high enough, other gases on the periodic table can become monatomic, such as hydrogen.Full Answer >
Gases and liquids are considered fluids because they both flow and move. The molecules comprising both gases and fluids are constantly in motion in random formations. The molecules continuously collide with each other and the sides of any container in which they are placed.Full Answer >
The primary difference between liquids and gases is that the constituent molecules of liquids are closer together and move less than those that make up gases. Liquids and gases behave in a number of similar ways, although both differ greatly from solids.Full Answer >
