They are hydroscopic and fume in air due to hydrolysis. The alkali metals react with halogens (group 17) to form ionic halides; the heavier chalcogens (group 16) to produce metal chalcogenides; and oxygen to form compounds, whose stoichiometry depends on the size of the metal atom. Go to our Alkali metal halides, or alkali halides, are the family of inorganic compounds with the chemical formula MX, where M is an alkali metal and X is a halogen.

The halides of other alkaline earth metals are fairly ionic and this character increases as the size of the metal increases. (ii) Halides. In the order of fluoride > chloride > bromide > iodide, the melting point decreases for the same alkali metal ion as the size of the halide ion increases. Lithium-ion is the most soluble and the solubility decreases with increasing size so that Cesium ion is the least water-soluble alkali metal ion. For the lithium halides in the second column, only lithium fluoride is insoluble, but a precipitate does not always form at these concentrations. For example, titanium tetrachloride melts at −25 °C and boils at 135 °C, making it a liquid at room temperature. For the calcium halides, only the fluoride is insoluble, forming a white precipitate. When alkali metal dissolves in liquid ammonia, the solution can acquire different colours. NLM . They are hydroscopic and fume in air due to hydrolysis.
