Liquid metal Liquid metal Liquid metal consists of alloys with very low melting points which form a eutectic that is liquid at room temperature. The standard metal used to be mercury, but gallium-based alloys, which are lower both in their vapor pressure at room temperature and toxicity, are being used as a replacement in various applications. A few elemental metals are liquid at or near room temperature. The most well known is mercury(Hg), which is molten above −38.8 °C (234.3 K, −37.9 °F). Others include caesium(Cs), which has a melting point of 28.5 °C (83.3 °F), rubidium (Rb)(39 °C [102 °F]), francium
Chlorine perchlorate perchlorates: Chlorine perchlorate Chlorine perchlorate is the chemical compound with the formula ClO. This chlorine oxide is an asymmetric oxide, with one chlorine atom in oxidation state +1 and the other +7, with proper formula ClOClO. It is produced by the photolysis of chlorine dioxide at room temperature with 436 nm ultraviolet light: Chlorine perchlorate can also be made the following reactions at −45 °C. Chlorine perchlorate is a pale greenish liquid which decomposes at room temperature. It is less stable than ClO and decomposes to O, Cl and ClO at room temperature. Chlorine perchlorate reacts with metal chlorides forming
