Polarity of Water
Structure of Water Molecules Water molecules are polarized, giving them slightly positive and slightly negative sides. This makes water even more susceptible to a charged rod’s attraction. As the water flows downward,…

Polar Molecule & Nonpolar Molecule
Polar molecule A polar molecule is a molecule with an unequal distribution of charge, resulting in the molecule having a positive end and a negative end. (ex. Water) Nonpolar molecule A nonpolar…
