Malleability and ductility of metals can be accounted due to

a. The capacity of layers of metal ions to slide over the other

b. The  interaction of electrons with metal ions in the other

c. The presence of electrostatic force

d. The crysyalline structure in metal

Ans.a

Explanation : When a metal is beaten it does not break but is convert into sheet. It is said to possess the property of melleability. Due to ductile nature, metals can be drawn into wires. These two properties of metals can be accounted due to the capacity of layers of metal ions to slide over the other.
