Which of the following statement is not correct for nitrogen ?

Options

A. Its electronegativity is very high
B. d-orbitals are available for bonding
C. it is a typical non-metal
D. its molecular size is small

Explanation

To determine which statement is not correct for nitrogen, we will analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Statement A: "Its electronegativity is very high."**
- **Analysis:** Nitrogen is known for its high electronegativity, which is approximately 3. This statement is correct.
- **Conclusion:** This statement is not the incorrect one.

2. **Statement B: "d orbitals are available for bonding."**
- **Analysis:** The atomic number of nitrogen is 7, which gives it the electronic configuration of 1s² 2s² 2p³. Nitrogen does not have any d orbitals available for bonding because d orbitals start from the third energy level (3d), and nitrogen only has electrons in the 1s, 2s, and 2p orbitals. Therefore, this statement is incorrect.
- **Conclusion:** This statement is the incorrect one.

3. **Statement C: "It is a diatomic nonmetal."**
- **Analysis:** Nitrogen is indeed a diatomic nonmetal, existing as N₂ in its gaseous form. This statement is correct.
- **Conclusion:** This statement is not the incorrect one.

4. **Statement D: "Its molecular size is small."**
- **Analysis:** As the first element in Group 15, nitrogen has a small molecular size compared to other elements in the same group. This statement is also correct.
- **Conclusion:** This statement is not the incorrect one.

### Final Answer:
The statement that is not correct for nitrogen is **Statement B: "d orbitals are available for bonding."**
