Atomic number of 15, 33,51 represents the following family:

Options

A. carbon family
B. nitrogen family
C. oxygen family
D. None of these

Explanation

To determine the family represented by the atomic numbers 15, 33, and 51, we will follow these steps:

### Step 1: Identify the Elements
- **Atomic Number 15**: This corresponds to Phosphorus (P).
- **Atomic Number 33**: This corresponds to Arsenic (As).
- **Atomic Number 51**: This corresponds to Antimony (Sb).

### Step 2: Determine the Group in the Periodic Table
- Phosphorus (P) is in Group 15 (or Group V) of the periodic table.
- Arsenic (As) is also in Group 15.
- Antimony (Sb) is also in Group 15.

### Step 3: Identify the Family
- Elements in Group 15 are commonly referred to as the Nitrogen Family or the Pnictogens. This family includes Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi).

### Conclusion
The atomic numbers 15, 33, and 51 represent the Nitrogen Family (Group 15) in the periodic table.

### Final Answer
The family represented by atomic numbers 15, 33, and 51 is the Nitrogen Family (Pnictogens).
