S Block Elements

\(\mathrm{LiF}\) and \(\mathrm{Li}_3 \mathrm{~N}\) are thermally stable compounds.

n the vapour phase \(\mathrm{BeCl}_2\) has a polymeric chain structure consisting of numerous \(\mathrm{BeCl}_2\) units.

Alkali and Alkaline earth metals cannot be produced by chemical reduction methods.

When equimolar aqueous solutions of \(\mathrm{SrCl}_2, \mathrm{MgCl}_2\) and \(\mathrm{BaCl}_2\) are taken and their \(\mathrm{pH}\) is recorded, \(\mathrm{BaCl}_2\) solution recorded the highest \(\mathrm{pH}\).
