Fluorine has the most electronegative element, Cl and Br
Cl, Si, Mg, Na
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.
Electronegativity is a characteristic property shared by ALL elements. Non-metals have the greatest (strongest force of electron attraction), and metals have the least (weak force of electron attraction)
FLourine is the most electronegative element so it likes to grab the electrons from other elements when it is in compounds. If you are comparing two different elements the periodic trend for strong electrnegativity tends to go to the right and up. The trend for the weakest electronegativity goes to the left and down on the periodic table so you could say that Francium is the least electronegative.
From greatest to least tendency to accept an electron, they are F, O, C, Li, and Be.

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)
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.
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.
From least to greatest: Inch-Feet-Yards-Miles
chlorine (greatest), bromine, sodium, potassium (least)

These number from least to greatest is 33.5,6.05,1,5,6 and 545. The decimals are the smallest numbers.
