The correct decreasing order of electronegativity

A
As>S>Al>Ca
B
S>Al>Ca>As
C
S>As>Al>Ca
D
Al>S>As>Ca
Answer
S>As>Al>Ca
Explanation
Solution
The electronegativity of elements generally increases across a period from left to right and decreases down a group from top to bottom.
- Calcium (Ca): Period 4, Group 2
- Aluminum (Al): Period 3, Group 13
- Arsenic (As): Period 4, Group 15
- Sulfur (S): Period 3, Group 16
Therefore the correct order is S > As > Al > Ca.
