Write an Explanation.
Electronegativity
Advertisements
उत्तर
Electronegativity is the tendency of an atom to attract the shared pair of electrons towards itself in a chemical bond. Elements with high electronegativity strongly pull electrons, while those with low electronegativity tend to lose electrons easily. Electronegativity decreases down a group due to increased atomic size, and increases across a period due to increasing nuclear charge.
