Francium
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.
Metals generally have low electronegativity values, with alkali metals like lithium, sodium, and potassium exhibiting some of the lowest. This is due to their tendency to lose electrons easily, making them more electropositive. In the periodic table, electronegativity decreases as you move down a group, further contributing to the low values seen in these metals.
iron
The element with the lowest ionization energy, electron affinity, and electronegativity is francium (Fr). Francium is an alkali metal located at the bottom of Group 1 in the periodic table, which gives it a very low tendency to attract electrons and hold onto its own. Its large atomic size and low effective nuclear charge contribute to these low values, making it the least electronegative element.
Chlorine has a high electronegativity, meaning it has a strong tendency to attract electrons. This property makes it likely to form a compound with an alkali metal through ionic bonding, where the alkali metal loses an electron to chlorine to achieve a more stable electron configuration.
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.
Barium
Francium has the greatest electropositivity and the lowest electronegativity.

iron
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.
Francium is considered as the most reactive metal; francium has the greatest electropositivity and the lowest electronegativity.
The element with the lowest electronegativity is lithium. Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself in a chemical compound. Lithium has the lowest electronegativity among the elements listed.
Atoms with the lowest electronegativity values located on the leftmost part of the Periodic Table. The atom with the lowest electronegativity belongs to Francium.
