 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.
