Question

which alkaline earth metal does not form peroxides​

Answer 1

Explanation:

All alkali metals form peroxides. The peroxides of all the alkali metals, with the exception of lithium, can be synthesized by direct oxidation of the metal with oxygen at atmospheric pressure. The reactivities of sodium, potassium, rubidium, and cesium result from the fact that these metals have large atomic radii and low ionization potentials. Lithium does not share such properties and, consequently, lithium peroxide can be synthesized only by the reaction of lithium hydroxide with hydrogen peroxide solutions. Methods for the synthesis of alkali metal peroxides have been known for a long time. In recent years, research has been directed toward the improvement of these methods and toward more precise determinations of the properties and structure of peroxides and their hydrates and peroxyhydrates.

Hey , heres ur answer

Lithium is the alkali metal which doesnot form peroxide.
