Francium has the highest Pauling electronegativity: 0,7.
Among the four elements listed, phosphorus has the highest electronegativity. Electronegativity is a measure of an atom's ability to attract and hold onto electrons, and phosphorus has a higher electronegativity value compared to francium, copper, and sodium.
Fluorine is the element with the highest electronegativity value.
Electronegativity increases as you go from the bottom left corner of the periodic table to the upper right corner. The element with the lowest electronegativity is thus francium (Fr). However, this element is radioactive, and so generally the least electronegative element that you can really use is cesium (Cs). Generally speaking, this whole first column (the alkali metals) all have very low electronegativities, but the lower down the column, the lower the electronegativity.(Francium may not be the least electronegative element due to the relativistic effects, which is evident from its ionization energy (> Cs) and standard electrode potential (
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
If only the monopositive ions are considered, helium would create the ion with highest electronegativity.

Chlorine is a group 17 element and has the highest electronegativity among the elements given.
The element with the highest electronegativity is fluorine.
If only the monopositive ions are considered, helium would create the ion with highest electronegativity.
Francium has the lowest electronegativity and fluorine the highest.
Fluorine has the highest electronegativity of all elements.
Flourine
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.
Francium, with atomic number 87, does not have the highest atomic number. When it was discovered, in 1939, scientists already knew of five elements with higher atomic numbers: radium (88), actinium (89), thorium (90), protactinium (91) and uranium (92). By the end of 2015, the highest atomic number was 118 - for ununoctium.
