In the periodic table, nitrogen belongs to which group

Options

A. Group-7
B. Group-1
C. Group-15
D. Group-8

Answer

To determine which group nitrogen belongs to in the periodic table, we can follow these steps:

### Step 1: Identify the Element
Nitrogen is represented by the symbol **N** and has an atomic number of **7**.

### Step 2: Determine the Electronic Configuration
The electronic configuration of nitrogen can be written as:
- **1s² 2s² 2p³**
This shows that nitrogen has a total of **5 valence electrons** (2 in the 2s orbital and 3 in the 2p orbital).

### Step 3: Identify the Block of the Element
Since nitrogen has its valence electrons in the p-orbital, it is classified as a **p-block element**.

### Step 4: Calculate the Group Number
For p-block elements, the group number can be calculated using the formula:
- **Group number = Number of valence electrons + 10**
In the case of nitrogen:
- **Number of valence electrons = 5**
- Therefore, **Group number = 5 + 10 = 15**

### Step 5: Conclusion
Thus, nitrogen belongs to **Group 15** of the periodic table.

### Final Answer
Nitrogen belongs to **Group 15**.
