Gold, electronegativity: 2.4
It is Fluorine.
astatine
beryllium
because fluorine is highly electronegative and is the most reactive non metal.
All metal has less number of proton when compared to non-metal, in another word all metal has low effective nucleus charge compared to non-metal, the high effective nucleus charge causes the non-metal has higher electronegative than metal as the term electronegative means the ability to accept electron from others and in order to do that the nucleus of the atom ( effective nucleus charge ) must be high enough. That explain why metal donate electron due to low electronegative and non-metal accept electron due to high electronegative.
fluorine is the most electronegative atom . therefore atoms closer to fluorine will be more electronegative.

beryllium
fluorine is most electronegative and cesium is least electronegative
because fluorine is highly electronegative and is the most reactive non metal.

It is sodium metal.
the atomic number for flourine, the most electronegative element, is 9.
An electronegative atom is an atom that can attract a bonding pair of electrons from another atom. Fluorine is the most electronegative element.
fluorine is the most electronegative atom . therefore atoms closer to fluorine will be more electronegative.
Fluorine. It is the most electronegative element.
Across a period, electronegativity increases. Hence oxygen is more electronegative than lithium. However fluorine is the most electronegative element on the periodic table.
