2019-4-9 · Zirconium is a chemical element with syol Zr and atomic nuer 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely reseles hafnium and, to a lesser extent, titanium.

Metals, Metalloids, and Nonmetals - Angelo State …

2010-5-12 · The elements can be classified as metals, nonmetals, or metalloids.Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire).Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid).

Alkali & Earth Metals - [PDF Document]

By sharing electrons, the atoms remain more or less electrically neutral. However, when an atom of a metal approaches an atom of a nonmetal, the more likely event is the transfer of one or more electrons from the metal atom to the nonmetal atom. The metal atom becomes a positively charged ion and the nonmetal atom becomes a negatively charged ion.

Hydrogen chloride — Wikipedia Republished // WIKI 2

2019-4-11 · Small amounts of HCl gas for laboratory use can be generated in an HCl generator by dehydrating hydrochloric acid with either sulfuric acid or anhydrous calcium chloride. Alternatively, HCl can be generated by the reaction of sulfuric acid with sodium chloride: NaCl + H 2 SO 4 → NaHSO 4 + HCl. This reaction occurs at room temperature.

Aluminium magnesium boride | Revolvy

Aluminium magnesium boride Aluminum magnesium boride or BAM is a chemical compound of aluminium, magnesium and boron. Whereas its nominal formula is AlMgB, the chemical composition is closer to AlMgB. It is a ceramic alloy that is highly resistive to wear and has an extremely low coefficient of sliding friction, reaching a record value of 0.02 in lubried AlMgB−TiB composites.

Hydrogen fluoride - Howling Pixel

Hydrogen fluoride is a highly dangerous gas, forming corrosive and penetrating hydrofluoric acid upon contact with moisture. The gas can also cause blindness by rapid destruction of the corneas.. French chemist Edmond Frémy (1814–1894) is credited with discovering anhydrous hydrogen fluoride while trying to isolate fluorine.Although Carl Wilhelm Scheele prepared hydrofluoric acid in large

Elements - Metals, Nonmetals and Metalloids
