Define electronegativity.
Advertisements
उत्तर १
Electronegativity is the ability of an atom in a chemical compound to attract a bond pair of electrons towards itself.
Electronegativity of any given element is not constant. It varies according to the element to which it is bound. It is not a measurable quantity. It is only a relative number
उत्तर २
Electronegativity is the tendency of an atom to attract shared pair of electrons. It is the property of bonded atom.
