1.0
The largest possible electronegativity difference for a bond to be considered covalent is around 1.7. When the electronegativity difference between two atoms in a bond exceeds this value, the bond is usually considered ionic rather than covalent.
Barium
Be (beryllium) is more reactive than Sr (strontium) among the alkali earth metals. Beryllium has a higher reactivity due to its small atomic size and high electronegativity, making it more likely to form bonds with other elements.
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.

Alkali Metal
Cesium has the lowest electronegativity among the alkali metals.
The alkali metal with the largest electronegativity is fluorine, found in Group 1 of the periodic table. Its low atomic size and high effective nuclear charge lead to a strong attraction for electrons, resulting in the highest electronegativity among alkali metals.
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.
The elements with low electronegativity are the metals, specifically the alkali metals and alkali earth metals. The elements further to the left of the periodic table will have lower electronegativity than those farther to the right.
The alkali metals have a low electronegativity and they easily loss an electron.
Barium belongs to the alkali earth metals family in the periodic table.
A metal.
This is francium because having a very lower electronegativity can loss easily an electron.
