Question

determine which of the following has the highest electronegativity. write out the full name. f or br

Explanation:

Step1: Recall electronegativity trend

Electronegativity increases across a period and decreases down a group in the periodic table. Fluorine (F) and bromine (Br) are in the same group (Group 17 - halogens), with F above Br.

Step2: Determine the more electronegative element

Since electronegativity decreases down a group, F is more electronegative than Br.

Answer:

Fluorine
