Malleability and ductility of metals can be accounted due to

Options

A. The capacity of layers of metal ions to slide over the other
B. The crystalline structure in metal
C. Presence of electrostatic with metal ions
D. Interaction of electrons with metal ions.

Answer

To answer the question about the malleability and ductility of metals, we can follow these steps:

### Step-by-Step Solution:

1. **Define Malleability and Ductility**:
- Malleability is the ability of a metal to be hammered or rolled into thin sheets without breaking.
- Ductility is the ability of a metal to be drawn into wires.

2. **Understand the Structure of Metals**:
- Metals consist of a lattice structure made up of metal ions surrounded by a 'sea' of delocalized electrons. This is often referred to as the metallic bond.

3. **Role of Delocalized Electrons**:
- The delocalized electrons are not bound to any specific metal ion; they can move freely throughout the structure. This mobility is crucial for the properties of malleability and ductility.

4. **Sliding of Metal Ions**:
- When a metal is subjected to stress (like hammering or pulling), the layers of metal ions can slide over each other due to the presence of these delocalized electrons. This sliding occurs without breaking the metallic bond, allowing the metal to change shape.

5. **Conclusion**:
- Therefore, the malleability and ductility of metals can be accounted for by the capacity of layers of metal ions to slide over one another, facilitated by the delocalized electrons.

### Final Answer:
The malleability and ductility of metals can be accounted due to the capacity of layers of metal ions to slide over one another.
