The Alkaline Earth Metals Be The name Beryllium comes from the Greek beryllos which is the name for the gemstone beryl. BIOF possesses the shortest UV cutoff edge (230 nm), and SIOF has the largest birefringence (cal. metal and the ligand, chiral alkaline earth metal complexes have been classified into three types (Figure 1.1) [1, 2, 5].

They are not found in their pure state in nature due to their reactivity but are found readily in ores. The hydroxides of alkaline earth metals therefore come under weak base category.
