Metals are malleable and ductile because their layers _ on applying pressure.

Explanation

Metals are malleable and ductile because their layers slip past each other on applying pressure. Malleability is the ability of a material to be hammered or rolled into sheets without breaking. Ductility is the ability of a material to be drawn into wires without breaking. oth malleability and ductility are due to the fact that the atoms in metals are held together by metallic bonds. Metallic bonds are formed by the delocalized electrons of the metal atoms. These delocalized electrons are free to move around, which allows the atoms to slide past each other easily. When pressure is applied to a metal, the layers of atoms can slide past each other without breaking the metallic bonds. This is why metals can be hammered, rolled, and drawn into wires.
