Understand the concept of electronegativity: Electronegativity is the ability of an atom to attract electrons towards itself in a chemical bond. In a water molecule (H₂O), oxygen is more electronegative than hydrogen.
Analyze the structure of a water molecule: A water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom. The chemical formula is H₂O.
Consider the distribution of electron density: Due to oxygen's higher electronegativity, it pulls the shared electrons in the covalent bonds closer to itself, creating a partial negative charge on the oxygen atom.
Determine the charge distribution: As the electrons are pulled towards the oxygen atom, the hydrogen atoms are left with a partial positive charge because they have less electron density around them.
Conclude the polarity of the molecule: The water molecule is polar, with the oxygen end having a partial negative charge and the hydrogen end having a partial positive charge.
