F , O , N , Cl , Br , C , S , I , H , P
F > O > N = Cl > Br > C = S = I > H = P
F ➞ Fluorine
O ➞ Oxygen
N ➞ Nitrogen
Cl ➞ Chlorine
Br ➞ Bromine
C ➞ Carbon
S ➞ Sulfur
I ➞ Iodine
H ➞ Hydrogen
P ➞ Phosphorous
[Note :➞ This order is in decreasing from up to down ex. Fluorine has greater value than oxygen ]
Electronegativity Values ➞
Fluorine ➞ 4.0
Oxygen ➞ 3.5
Nitrogen ➞ 3.0
Chlorine ➞ 3.0
Bromine ➞ 2.8
Carbon ➞ 2.8
Sulfur ➞ 2.5
Iodine ➞ 2.5
Hydrogen ➞ 2.1
Phosphorous ➞ 2.1
❊ Electronegativity is an index of the tendency of an atom to attract electrons.
❊ Electronegativity values decrease from top to bottom in a group of elements.
