Would someone please explain in detail the relationship between the two? I understand that atomic radius is related to ionisation energy but I can't see how it may be related to electronegativity.

And it appears that they are not inversely proportional to each other, but I couldn't find any explanation for this (or for the relationship between the two) online.

Electronegativity increases across a period and decreases down a group. Like ionisation energy electronegativity is also affected by shielding and nuclear charge as well as atomic radius. For example, electronegativity decreases down a group as atomic radius increases (nuclear charge increases but shielding also increases - hence cancelling each other out). A larger atomic radius means that the bonding electrons are further from the attractive pull of the nucleus so are less strongly attracted.

Electronegativity is the ability to attract bonding pairs of electrons.

If the atomic radius is smaller, then the nucleus can attract electrons more easily, and they’ll be held closer and more strongly. These smaller atoms are more electronegative.

If the atomic radius is larger, there are more shells and shielding has a big effect, meaning that the bonding electrons are not held so strongly to the nucleus. These larger are atoms are not very electronegative.

Atomic radius increases down a group.
