what kind of elecrtical charge is found on the oxygen atom of a polar water molecule
To determine the kind of electrical charge on the oxygen atom of a polar water molecule, we first need to understand the concept of polarity in molecules.
The oxygen atom in a water molecule has a slightly negative charge because it pulls the shared electrons toward itself more strongly than the hydrogen atoms. This is due to oxygen's greater electronegativity compared to hydrogen. As a result, the oxygen atom becomes partially negative (δ-) while the hydrogen atoms become partially positive (δ+). This separation of charges in a molecule is called polarity, and in a water molecule, it creates a dipole moment.
So, to answer your question, the electrical charge on the oxygen atom of a polar water molecule is partially negative (δ-).
