Select the correct answer. Why don't metals break when pounded into sheets or drawn into wires? A. The electrons in metals are shared so that the bond between them is too strong to be broken by pounding. B. The electrons in metals allow the cations to slide past and thereby reduce the repulsive force between them. C. The electrons in metals are either given up or taken up while bonding, creating a bond too strong to be broken by pounding. D. They form molecules in which each atom is bonded to many other atoms, forming a sturdy structure which doesn't break on poundi E. They form molecules which have a very high boiling and melting point, which makes them resistant to breaking.

Answer 1

The correct answer is B. The electrons in metals allow the cations to slide past and thereby reduce the repulsive force between them.Metals have a unique structure where the electrons are delocalized, meaning they are not bound to any specific atom and can move freely throughout the metal lattice. This delocalization of electrons creates a "sea of electrons" that allows the metal atoms (cations) to slide past each other without breaking the metallic bond.When metals are pounded into sheets or drawn into wires, the atoms are rearranged, but the delocalized electrons can still move freely and maintain the metallic bond. This allows the metal to be deformed without breaking, as the repulsive forces between the cations are reduced by the movement of the delocalized electrons.The other options are incorrect because they do not accurately describe the behavior of metals when subjected to deformation.
