Malleability and ductility of metals can be accounted due to

Options

  1. Athe presence of electrostatic force
  2. Bthe crystalline structure in metal
  3. Cthe capacity of layers of metal ions to slide over the other
  4. Dthe interaction of electrons with metal ions in the lattice

Correct answer

C. the capacity of layers of metal ions to slide over the other

Step-by-step solution

In metallic bonds, the valence shell electrons are delocalised and shared between many atoms. These delocalised electrons allow the metal atoms to slide past one another without being subjected to strong repulsive forces. The malleability and ductility of metals is due to this sliding capacity of the delocalised electrons.
