Which one element has the highest electronegativity value A. Lithium B. Nitrogen C. Chlorine D. Fluorine

Lithium is a metal with a low electronegativity value. This means that lithium is not very likely to attract electrons, and it is therefore not very electronegative.

Nitrogen is a non-metal with a moderate electronegativity value. This means that nitrogen is somewhat likely to attract electrons, but it is not as electronegative as fluorine, oxygen, or chlorine.

Chlorine is a non-metal with a high electronegativity value. This means that chlorine is very likely to attract electrons, and it is therefore more electronegative than lithium, nitrogen, or oxygen.
