Question

Which of the following has highest electronegativity?

a) F

b) Cl

c) Br

d) I​

Answer 1

Answer:

Thus, fluorine is the most electronegative element, while francium is one of the least electronegative. (Helium, neon, and argon are not listed in the Pauling electronegativity scale, although in the Allred-Rochow scale, helium has the highest electronegativity.)

Answer 2

Answer:

The highest electronegativity has Option (a) F.

Explanation:

What is electronegativity?

• Electronegativity is the property of atom or functional group to accept electron from another atom or functional group.

Why Halogens electronegativity is highest in the periodic table?

• Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I) and Astatine (At) are the atoms of Halogen group (Group 17) in the periodic table.
• These five atoms are toxic and non-metallic.

• Halogen atoms have highest electronegativity because they need only one electron to complete their octet so they have higher attraction towards electron.
• In halogen group electronegativity of atoms are as below:

1. Fluorine (F) : 4.0
2. Chlorine (Cl) : 3.0
3. Bromine (Br) : 2.8
4. Iodine (I) : 2.5
5. Astatine (At) : 2.2

So, from above table we can say that electronegativity of halogens are in manner of : F>Cl>Br>I>At

So, option A - F (Fluorine) is correct because it has highest electronegativity.
