Options

A. `ns^(2)np^(2)`
B. `ns^(2)np^(1)`
C. `ns^(2)np^(3)`
D. `ns^(2)np^(5)`

Answer

To determine the valence shell electronic configuration of VA group elements (Group 15 elements), we will analyze the electronic configurations of the elements in this group step by step.

### Step 1: Identify the Group 15 Elements
The VA group, also known as Group 15, includes the following elements:
- Nitrogen (N)
- Phosphorus (P)
- Arsenic (As)
- Antimony (Sb)
- Bismuth (Bi)
- Moscovium (Mc)

### Step 2: Write the Electronic Configuration for Each Element
1. **Nitrogen (N)**: Atomic number = 7
- Electronic configuration: 1s² 2s² 2p³
- Valence shell configuration: ns² np³ → 2s² 2p³

2. **Phosphorus (P)**: Atomic number = 15
- Electronic configuration: 1s² 2s² 2p⁶ 3s² 3p³
- Valence shell configuration: ns² np³ → 3s² 3p³

3. **Arsenic (As)**: Atomic number = 33
- Electronic configuration: [Ar] 3d¹⁰ 4s² 4p³
- Valence shell configuration: ns² np³ → 4s² 4p³

4. **Antimony (Sb)**: Atomic number = 51
- Electronic configuration: [Kr] 4d¹⁰ 5s² 5p³
- Valence shell configuration: ns² np³ → 5s² 5p³

5. **Bismuth (Bi)**: Atomic number = 83
- Electronic configuration: [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³
- Valence shell configuration: ns² np³ → 6s² 6p³

### Step 3: Generalize the Valence Shell Configuration
From the electronic configurations of the elements in Group 15, we can see a pattern:
- The valence shell configuration for all these elements can be generalized as **ns² np³**.

### Conclusion
Thus, the valence shell electronic configuration of VA group elements is **ns² np³**.

### Answer
The correct answer is: **ns² np³**.
