Solution
Correct Answer:
F > O > N > C
- Concept: Electronegativity is the tendency of an atom to attract shared electrons in a covalent bond.
- Periodic Trend: Increases from left to right across a period and decreases down a group.
- Relative Values:
- Fluorine (F): 4.0 (Highest)
- Oxygen (O): 3.5
- Nitrogen (N): 3.0
- Carbon (C): 2.5
- Conclusion: The decreasing order is F>O>N>C.
