WebLead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. WebSince the O 2– ion is smaller than the Se 2– ion, the Al 2 O 3 has a shorter interionic distance than Al 2 Se 3 and has, therefore, larger lattice energy. Another example is zinc oxide, ZnO, compared to NaCl.
