By hybridization, we mean the hybridization of

Options

A. orbitals
B. electrons
C. both orbitals and electrons
D. None of these

Explanation

### Step-by-Step Solution:

1. **Understanding Hybridization**:
- Hybridization is the process of mixing atomic orbitals of the same atom that have slightly different energies. This mixing leads to the formation of new orbitals that are of equal energy and identical shape.

2. **Definition of Hybrid Orbitals**:
- The new orbitals formed through hybridization are known as hybrid orbitals. These orbitals are used in the formation of chemical bonds.

3. **Types of Hybridization**:
- There are several types of hybridization based on the number and types of atomic orbitals involved:
- **sp Hybridization**:
- Involves the mixing of one s orbital and one p orbital from the same shell.
- This results in the formation of two equivalent hybrid orbitals that have a linear shape.
- **sp² Hybridization**:
- Involves the mixing of one s orbital and two p orbitals from the same shell.
- This results in the formation of three equivalent hybrid orbitals that have a trigonal planar shape.
- **sp³ Hybridization**:
- Involves the mixing of one s orbital and three p orbitals from the same shell.
- This results in the formation of four equivalent hybrid orbitals that have a tetrahedral shape.

4. **Conclusion**:
- Therefore, by hybridization, we mean the hybridization of atomic orbitals belonging to the same atom.

### Final Answer:
By hybridization, we mean the hybridization of atomic orbitals.
