Question

what is the element with the highest electronegativity value?
cesium
calcium
fluorine
helium

Explanation:

Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond. Fluorine has the highest electronegativity value among the given options. Cesium is a metal with low electronegativity. Calcium is also a metal with relatively low electronegativity. Helium is a noble gas and generally does not form bonds (so its electronegativity is not considered in the traditional bonding sense like the other elements here).

Answer:

fluorine
