But, the bicarbonates of alkaline earth metals … The alkaline earth metals are very reactive, although less so than the alkali metals. Solubility of bicarbonates: bicarbonates of alkali metals are less soluble than their corresponding carbonates. Because BeO and MgO are much more inert than the other group 2 oxides, they are used as refractory materials in applications involving high temperatures and mechanical stress. The lattice energy remains constant because sulphate ion is so large, so that small change in cationic sizes do not make any difference. The alkaline earths possess many of the characteristic properties of metals.Alkaline earths have low electron affinities and low electronegativities.As with the alkali metals, the properties depend on the ease with which electrons are lost.The alkaline earths have two electrons in the outer shell. asked May 29, 2019 in Chemistry by Sweety01 ( 69.9k points) s-block elements This approach of breaking down a problem has been appreciated by majority of our students for learning Differences between alkali and alkaline earth metals concepts.
