state anomalous property of beryllium

1.	state anomalous property of beryllium
Answer» Compounds of lithium are partially soluble in water whereas the alkali metals are highly soluble in water.Beryllium: Theanomalous properties of berylliumis mainly due to its small size, high electronegativity, high ionization energy and high polarizing power compared to the other elements in the block. The coordinate number of beryllium is not more than 4 whereas other alkali metals have coordinate number of 6.• The melting point and boiling points are higher when compared to the other elements of the group.• They form covalent bonds whereas the other members form of the group form ionic bonds.• Be does not react with water like the other companions of the group thanks
