In a covalent solid the lattice points are occupied by

Options

A. atoms
B. ions
C. molecules
D. electrons

Explanation

### Step-by-Step Solution:

1. **Understanding Covalent Solids**:
- Covalent solids are a type of crystalline solid where the atoms are bonded together by covalent bonds. This means that the atoms share electrons to achieve stability.

2. **Identifying Lattice Points**:
- In a crystal lattice, the points at which the atoms are located are referred to as lattice points. In covalent solids, these lattice points are occupied by atoms.

3. **Bonding in Covalent Solids**:
- The atoms at the lattice points are not isolated; they are covalently bonded to neighboring atoms. This forms a continuous network throughout the solid.

4. **Network Solids**:
- Due to the extensive bonding between the atoms, covalent solids are often referred to as network solids. This is because the covalent bonds create a three-dimensional network that extends throughout the entire crystal.

5. **Conclusion**:
- Therefore, in a covalent solid, the lattice points are occupied by atoms.

### Final Answer:
The lattice points in a covalent solid are occupied by **atoms**.
