Electronegativity, in general, is the measure of an atom's ability to attract and hold onto electrons within a chemical bond. When ionic compounds, such as table salt (NaCl), are introduced to water, the δ+ hydrogen atoms are attracted to the negatively charged chloride ions, while the δ- oxygen atoms are attracted to the positively charged sodium ions.
Understanding Water Dipole Moment Through Electronegativity
Hydrogen Bonding: The Consequence of Polarity The high electronegativity of oxygen and the resulting polarity of the O-H bonds enable water molecules to engage in hydrogen bonding. This process, known as solvation or hydration, is fundamental to countless biological and chemical processes.
Hydrogen, by contrast, has a much lower value of around 2. Quantifying the Difference: Pauling vs.

Allred-Rochow Electronegativity Scale Oxygen (O) Hydrogen (H) Difference (ΔEN) Pauling 3. In the case of water, the significant difference in electronegativity between oxygen and hydrogen is the reason for the molecule's polar nature, which in turn explains water's remarkable solvent capabilities and its unique physical properties.
