Cesium (Caesium) is a soft, silvery-gold alkali metal with a melting point of 28 °C (82 °F). Cesium is used in various industries, from the oil industry as cesium formate in drilling fluid, atomic clocks, centrifugation fluids, and cesium vapor thermionic generators, which convert heat energy to electrical energy.
Cesium is a naturally occurring element found combined with other elements in rocks, soil, and dust in low amounts. Naturally occurring cesium is not radioactive and is referred to as stable cesium.
Cesium, the most electropositive and least abundant of the five naturally occurring alkali metals, was discovered spectroscopically in 1860. The first cesium metal was produced in 1881. Because cesium is not mined domestically, the United States is completely dependent on imports. Historically, the most important use for cesium has been in research and development, primarily in chemical and electrical applications.
Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6.
It is a steely-grey, lustrous, hard and brittle transition metal.
Chromium is also the main additive in stainless steel, to which it adds anti-corrosive properties.
Chromium is also highly valued as a metal that is able to be highly polished while resisting tarnishing. Polished chromium reflects almost 70% of the visible spectrum, with almost 90% of infrared light being reflected.
The name of the element is derived from the Greek word χρῶμα, chrōma, meaning color, because many chromium compounds are intensely colored.
Chromium is a naturally occurring element found in rocks, animals, plants, soil, and in volcanic dust and gases. Chromium is present in the environment in several different forms. The most common forms are chromium(0), chromium(III), and chromium(VI).
No taste or odor is associated with chromium compounds. Chromium(III) occurs naturally in the environment and is an essential nutrient.
Chromium(VI) and chromium(0) are generally produced by industrial processes.
The metal chromium, which is the chromium(0) form, is used for making steel. Chromium(VI) and chromium(III) are used for chrome plating, dyes and pigments, leather tanning, and wood preserving.
Oxygen is the chemical element with the symbol O and atomic number 8, meaning its nucleus has 8 protons.
Oxygen is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
Dioxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone.
Oxygen was isolated by Michael Sendivogius before 1604, but it is commonly believed that the element was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774.
