Answer: (B) Diamond
Covalently linked atoms make up network solids. They are bonded in such a way that they resemble a continuous network extending through their entire structure.
Diamond:
- Diamond is a giant crystalline solid in which constituent atoms are held together by covalent bonds of a non-metal carbon.
- It has covalent bonding extending throughout the crystal-like structure.
- There is a strong and directional connection between two adjacent atoms of the crystal, which results in a covalent bond helping the atoms to be held strongly at their positions.
- Thus, it has a very high melting point which indicates that diamond is a network solid.
