Q. Arrange F, Cl, O, N in the decreasing order of electronegativity-

 2999  177 Classification of Elements and Periodicity in Properties Report Error

Solution:

Electronegativity(E.N) of elements are; .
Therefore, the trend is : .
This can be explained as, on moving from left to right across a period, the E.N increases and also on moving down a group from top to bottom the E.N decreases.
