Nonmetallic elements of Group

With the valence electron configuration s p2 the nonmetallic elements of group 14 can form compounds with four tetrahedrally directed covalent bonds. Only carbon forms strong multiple bonds, and its compounds show many differences in structure and properties from those of Si and Ge. Like the metallic elements of the group (Sn and Pb), germanium has some stable divalent compounds.

Rnally, we examine boron—the sole nonmetallic element of group 3A. 

Sulfur [7704-34-9] S, a nonmetallic element, is the second element of Group 16 (VIA) of the Periodic Table, coming below oxygen and above selenium. In massive elemental form, sulfur is often referred to as brimstone. Sulfur is one of the most important taw materials of the chemical industry. It is of prime importance to the fertilizer industry (see Fertilizers) and its consumption is generally regarded as one of the best measures of a nation s industrial development and economic activity (see Sulfur compounds Sulfurremoval and recovery Sulfuric acid and sulfur trioxide).
