Fluorine has the most electronegative element, Cl and Br
if its for apex learning then the answer is bromine
Electronegativity is kind of a "made-up" thing as opposed to an actual quantity that can be experimentally measured. Fluorine is usually considered to have the highest electronegativity, though the precise value depends on exactly what definition and scale you're using and for "spectroscopic electronegativity" neon actually has the highest electronegativity of all.
The two elements with the largest electronegativity difference between their atoms are fluorine (F) and cesium (Cs). Fluorine is the most electronegative element on the periodic table, while cesium is one of the least electronegative elements.
Barium
Elements at the center of a period tend to have the highest electronegativity and smallest atomic radii compared to the other elements in the period. Additionally, these elements often possess a stable electron configuration.

The electronegativity from least to highest : Ba, Be, Bi, B, Br The electronegativity of an element is a measurement of how its atoms attract electrons. This is based on the atomic weight (width of the atomic nucleus) and the distance of its valence electrons from the nucleus. As displayed on the Periodic Table, elements generally increase in electronegativity as you move across (left to right), and decrease as you go down the table. (Only aluminum does not follow this in this set of elements.) (see related link)
If you want to ask questions about "which answer", then I suggest that you make sure that there is at least one answer that is following.
The electronegativity of astatine is 2.2 on the Pauling scale, making it one of the least electronegative elements. It is part of the halogen group and exhibits similar properties to iodine.

The electronegativity difference between fluorine and francium is approximately 3.9. Fluorine is the most electronegative element on the periodic table, while francium is one of the least electronegative. This significant difference in electronegativity contributes to the reactivity and chemical behavior of these elements.
Lithium has a lower electronegativity than krypton. The electronegativity for lithium is 0.98; the electronegativity for krypton is 3.0. Note that most noble gases in group 18 have no electronegativity at all since the do not make compounds. However, since krypton and xenon do make compounds under some circumstances, they do have a measurable electronegativity.
Elements at the center of a period tend to have the highest electronegativity and smallest atomic radii compared to the other elements in the period. Additionally, these elements often possess a stable electron configuration.
The molecules with the least kinetic energy are in solid form, followed by liquid, and then gas with the greatest kinetic energy.
