Electronegativity

From the word electronegativity it can imagine or guess about the meanings of electronegativity. Simply it means the capability of any atom to becoming negatively charged by attracting electron closer to it. In an covalent bond two or more atoms bonded with each other by sharing of electron. An electron cloud exists between two atoms. Each electron will not equally show an attraction with electron cloud. The atom that have higher attraction with electron, the electron cloud will get more closer to it. Hence, it will be partially negatively charged and rest will be partiality positively charged. Hence, Electronegativity can be defined as the attraction of an atom towards the electron in electron pair bond that enables electron cloud to become more dense surrounding this atom. For more density of the electron cloud near the high electronegative atom, it shows partially negatively charged.In chemistry there have a wide range of importance of electronegativity of atom. Electronegativity helps to predict the polarity, ionic character of covalent bond, inductive effects, determining the shapes of molecule.
