Electronegativity increases while atomic radius increases
Electronegativity decreases while atomic radius decreases
Electronegativity decreases while atomic radius increases
Electronegativity remains constant while atomic radius increases
Understanding the Answer
Let's break down why this is correct
When you go down a group, new electron shells are added. Other options are incorrect because Some think bigger atoms pull electrons harder, so electronegativity goes up; One might think that if the radius shrinks, electronegativity drops too.

Definition
Electronegativity measures an atom's ability to attract shared electrons in a molecule. It influences bond polarity and chemical reactions. Electronegativity trends across periods and groups provide insights into the nature of chemical bonds and the behavior of compounds.
