While if the electronegativity difference is too high between A and B then A being more electronegative than B dragged the electron pair towards itself completely and has complete control of both electrons. If the electronegativity of both elements A and B are equal, then they form a normal shared covalent bond. These types of bonds are called polar bonds or polar covalent bonds. If two atoms are bonded together and one atom is more electronegative than another bonded atom, then the electron density of the bond will shift slightly towards the more electronegative atom.įor example, if two atoms or elements A and B are bonded together and A is slightly more electronegative than B then the electron pair will slightly shift towards A and it will get a slightly negative charge( Aδ-)while B will get a slightly positive charge( Bδ+). Pauling defined electronegativity as “the power of an atom in a molecule to attract electrons to itself.” Thus, we can say the electronegativity of an atom is of relative value concerning that other atom to which it is bonded. Oxygen with its high electronegativity and hydrogen with its high electropositivity tends to hold each other together resulting in the formation of water.Įlectronegativity is one of the important properties of an element or atom as it gives information about the binding nature of an element or atom.Įlectronegativity is the measure of an element’s ability to attract a bonding pair of electrons towards itself. This bonding which is highly affected by electronegativity is something that holds it together. Wondering what keeps the water in its form? Well, it is the bonding between hydrogen and oxygen that forms the water.
