The electronegativity of sodium (Na) is approximately 0.93 on the Pauling scale. Electronegativity is a measure of an atom’s ability to attract and hold onto electrons when it is part of a compound.
Sodium is an alkali metal located in group 1 of the periodic table. It has a relatively low electronegativity compared to nonmetals. This low value indicates that sodium does not attract electrons very strongly. In the case of sodium, it tends to lose its single valence electron to achieve a stable electron configuration, which is characteristic of metals.
In summary, the low electronegativity of sodium highlights its tendency to form ionic bonds with nonmetals, such as chlorine, rather than covalent bonds.
