Aside from conductivity, metals have quite varied properties. Some are soft and
easily deformed by pressure or impact, or malleable (Cu, in fcc structure), whereas
others are hard and brittle, more likely to break rather than bend (Zn, anhcp structure).
However, most can be shaped by hammering or bending. This is possible because the
bonding in metals is nondirectional; each atom is bonded to all neighboring atoms,
rather than to individual atoms, as is the case in discrete molecule. Whern force is
applied, the atoms can slide over each other and realign into new structures with nearly
