Shows both the reactions and properties of some chemical elements. The reactions of the other alkali metals do not yield the oxides M 2 O(s). When heated alkali metals are placed into jars of oxygen gas, they will burst into flames. Potassium tarnishes... very quickly. Alkali metals are so-called because when they react with water, they create highly alkaline substances. The alkaline earth metals all react with the halogens to form ionic halides, such as calcium chloride (CaCl 2 ), as well as reacting with oxygen to form oxides such as strontium oxide ( SrO ).

Metal peroxides are metal-containing compounds with ionically- or covalently-bonded peroxide (O 2− 2) groups.This large family of compounds can be divided into ionic and covalent peroxide. They can all be cut easily with a knife due to their softness, exposing a shiny surface that tarnishes rapidly in air due to oxidation by atmospheric moisture and oxygen (and in the case of lithium, nitrogen). The elements of Group 2 are beryllium, magnesium, calcium, strontium, barium, and radioactive radium. This resource is designed for UK teachers. In this article, we will explain the electronic configurations, ionization enthalpy, hydration enthalpy and atomic, ionic radii and other physical and chemical properties of the group one alkali metals. Another important reaction is catalytic combustion of soot, where the alkali metal itself can involve the oxidative process through formation of carbon–oxygen complexes (C–O–M, with M alkali metals) as the active sites and further enhance the activity of soot oxidation [34,35].
