These metals, with their relatively low melting temperatures, offer unique properties that enable them to be easily manipulated, cast, and alloyed, opening up diverse ...
Because of this, the melting points increase going from Na to Al; Si has the highest melting point due to its giant molecular structure in which each Si atom is held to its neighboring Si atoms by four strong covalent bonds; P, S, Cl and Ar are non-metallic elements and exist as simple molecules (P 4, S 8, Cl 2 and Ar as a single atom)
The final value of the melting range is at the highest the melting point of the pure solid, but is often lower, reflecting the depressed melting point of the bulk solid. For example, a solid that is (20%) compound A and (80%) compound B would have a final melting temperature of point c in Figure 6.7b.
