Which one of these diagrams represents a pure metal?Diagram b is a pure metal – the atoms are arranged in a regular lattice. Whenpressure is applied (by hammering the metal) the layers can slide over eachother – this is why metals are malleable and ductile.But when the metal is an alloy (diagrams a, c, and d) new atoms enter thelattice and the layers can no longer slide easily.
