Which of the following elements has maximum
electronegativity?

Options

A. Al
B. S
C. Si
D. P

Explanation

To determine which of the given elements has the maximum electronegativity, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Electronegativity**: Electronegativity is defined as the tendency of an atom to attract shared electrons in a chemical bond.

2. **Identify the Elements**: The elements mentioned in the question are Aluminum (Al), Silicon (Si), Phosphorus (P), and Sulfur (S).

3. **Locate the Elements in the Periodic Table**: All these elements are located in the third period of the periodic table:
- Aluminum (Al) - Atomic number 13
- Silicon (Si) - Atomic number 14
- Phosphorus (P) - Atomic number 15
- Sulfur (S) - Atomic number 16

4. **Trend of Electronegativity**: Electronegativity increases as you move from left to right across a period in the periodic table. This is because the elements on the right side have a greater ability to attract electrons due to their higher nuclear charge and the increasing number of valence electrons.

5. **Determine the Position of Each Element**:
- Aluminum has 3 valence electrons.
- Silicon has 4 valence electrons.
- Phosphorus has 5 valence electrons.
- Sulfur has 6 valence electrons.

6. **Identify the Element with Maximum Electronegativity**: Since electronegativity increases from left to right, Sulfur (S), being the rightmost element in the third period with 6 valence electrons, has the highest electronegativity among the given elements.

7. **Conclusion**: Therefore, the element with the maximum electronegativity among the given options is **Sulfur (S)**.

### Final Answer:
**Sulfur (S)** has the maximum electronegativity among the given elements.
