Electronegativity generally increases down the group.
False
Let's discuss the relation between electronegativity and Atomic Radius.
As the atomic radius of the element increases the electronegativity value decreases.
The electronegativity value increases as the effective nuclear charge on the atomic nucleus increases. Electronegativity α Effective nuclear charge (Zeff)
Electronegativity is inversely proportional to atomic radius because effective nuclear charge decreases as atomic radius increases.
We know that atomic radius increases down the group.
Therefore, electronegativity should decrease down the group.
