CESIUM :)
The single "most likely" element that would form an ionic compound with fluorine is cesium, or possibly francium if enough of it could be collected. This is because cesium, among stable elements, has the lowest electronegativity and fluorine has the highest electronegativity. However, any alkali or alkaline earth metal element in fact readily forms an ionic compound with fluorine, as do many other metals.
cesium
There is no reaction between the two chemicals.
Cesium has a low electronegativity because it is a highly reactive alkali metal. Alkali metals typically have low electronegativities due to their tendency to lose electrons easily.
Cesium is a cation, as it has a positive charge due to losing an electron.
Cesium has the lowest electronegativity among the elements listed. Helium has the lowest electronegativity overall as it is a noble gas and does not typically form bonds. Calcium has higher electronegativity than cesium but lower than fluorine, which has the highest electronegativity among the listed elements.
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.
Fluorine is the most electronegative element and not a metal. Among metals, the most electronegative is cesium.
Fluorine is the most electronegative element out of the options provided (cesium, boron, sulfur, fluorine, barium). It has the highest electronegativity value on the Pauling scale, indicating its strong ability to attract electrons in a chemical bond.
Generally speaking, non-metals have high electronegativity and metals have low ones. Fluorine (F) has the highest electronegativity of any element, and cesium (Cs) has the lowest.
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 (

Lithium does not have the lowest electronegativity. It has an electronegativity of around 1.0 on the Pauling scale. Francium is typically considered to have the lowest electronegativity among the elements.
The chemical formula for fluorine is F2 and for cesium it is Cs.
When cesium and fluorine react, they form the ionic compound cesium fluoride (CsF).
The formula name for the element CsF is Caesium fluoride.
