Caesium | Project Gutenberg Self-Publishing - eBooks

Caesium or cesium [note 1] is a chemical element with syol Cs and atomic nuer 55. It is a soft, silvery-gold alkali metal with a melting point of 28 °C (82 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. [note 2] Caesium is an alkali metal and has physical and chemical properties similar to those of rubidium and potassium.

Nonmetal - Wikipedia

2019-4-17 · In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Chemically, nonmetals

Germanium - Howling Pixel

Four tetrahalides are known. Under normal conditions GeI 4 is a solid, GeF 4 a gas and the others volatile liquids. For example, germanium tetrachloride, GeCl 4, is obtained as a colorless fuming liquid boiling at 83.1 °C by heating the metal with chlorine. All the tetrahalides are readily hydrolyzed to hydrated germanium dioxide. GeCl 4 is used in the production of organogermanium compounds.

Hydrogen sulfide — Wikipedia Republished // WIKI 2

2019-4-12 · Hydrogen sulfide is slightly denser than air; a mixture of H 2 S and air can be explosive. Hydrogen sulfide burns in oxygen with a blue flame to form sulfur dioxide (SO 2) and water.In general, hydrogen sulfide acts as a reducing agent, especially in the presence of base, which forms SH −.. At high temperatures or in the presence of alysts, sulfur dioxide reacts with hydrogen sulfide to

Caesium or cesium [note 1] is a chemical element with syol Cs and atomic nuer 55. It is a soft, silvery-gold alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. [note 2] Caesium is an alkali metal and has physical and chemical properties similar to those of rubidium and potassium.

Binary compounds of hydrogen - WikiVisually

Hydrogen solutions []. Hydrogen has a highly variable solubility in the elements. When the continuous phase of the solution is a metal, it is called a metallic hydride or interstitial hydride, on account of the position of the hydrogen within the crystal structure of the metal.In solution, hydrogen can occur in either the atomic or molecular form.

Actinide - IPFS

This metal was discovered not by its own radiation but by the radiation of the daughter products. [28] [29] Owing to the close similarity of actinium and lanthanum and low abundance, pure actinium could only be produced in 1950. The term actinide was probably introduced by Victor Goldschmidt in 1937. [30] [31]
