a list of metals

Although most metals are usually electropositive in nature and lose electrons in a chemical reaction they do not react with the same vigour or speed. Metals display different reactions towards different substances. The greater the ease with which an element loses its electrons ..

Oxygen (or dioxygen) has the following physical properties. Oxygen is colorless, odorless and a tasteless diatomic gas under normal conditions. Oxygen is slightly heavier than air. Its density relative to air is 1.1053. Oxygen is sparingly soluble in water. 30 mL of oxygen in one liter of ..

. H 2 S undergoes dissociation and the hydrogen ions are lost. The particles become negatively charged due to (S 2 - ) which are left on the colloidal particles. v) Colloidal particles get charged by the simple process of electron capture. The colloidal particles may acquire charge by capturing ele..

The SI unit of density is kg m - 3 and in the cgs system, the unit of density is g cm -3 . The densities of different substances vary widely. Densities of most of the solids are greater than that of liquids, though there are exceptions. Densities of wood, wax and cork are less than that of water an..
