Question

Identify the reason for the gradual change in electronegativity in halogens

down the group.

a) Electronegativity increases down the group due to decrease in atomic

size

b) Electronegativity decreases down the group due to decrease in

tendency to lose electrons

c) Electronegativity decreases down the group due to increase in atomic

radius/ tendency to gain electron decreases

d) Electronegativity increases down the group due to increase in forces of

attractions between nucleus & valence electrons​

Answer 1

Explanation:

c) Electronegativity decreases down the group due to increase in atomic radius.

Answer 2

Answer:

b) Electronegativity decreases down the group due to decrease in

tendency to lose electrons.
