In a diamond. each carbon atom is bonded to:
A) two other carbon atoms
B) three other carbon atoms
C) four other carbon atoms
D) five other carbon atoms

Options

A. two other carbon atoms
B. three other carbon atoms
C. four other carbon atoms
D. five other carbon atoms

Answer

To solve the question regarding how many carbon atoms are bonded to each carbon atom in a diamond, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Carbon's Valency**:
- Carbon has an atomic number of 6, which means it has 4 electrons in its outer shell. The valency of carbon is 4, which indicates that each carbon atom can form four covalent bonds with other atoms.

**Hint**: Remember that the valency of an element indicates how many bonds it can form with other atoms.

2. **Identifying the Structure of Diamond**:
- Diamond is one of the allotropes of carbon. In its structure, each carbon atom is tetrahedrally coordinated, meaning it forms bonds in a three-dimensional arrangement.

**Hint**: Visualize the diamond structure as a three-dimensional network where each atom is at the center of a tetrahedron.

3. **Bonding in Diamond**:
- In diamond, each carbon atom is bonded to four other carbon atoms. This is due to the tetrahedral arrangement, where each carbon atom shares its four valence electrons with four neighboring carbon atoms.

**Hint**: Think of the diamond structure as a strong lattice where each atom is connected to four others, providing its hardness.

4. **Conclusion**:
- Based on the bonding structure of diamond, the correct answer to the question is that each carbon atom is bonded to four other carbon atoms.

**Final Answer**: C) four other carbon atoms.
