Detailed explanation-1: -The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction.
Detailed explanation-2: -Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.
Detailed explanation-3: -Some molecules have positive and negative ends too, and when they do, we call them polar. If they don’t, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel). The two magnets in the image above will attract because their opposite poles are near.
Detailed explanation-4: -The oxygen is the negative end of the molecule, while the area between the hydrogen atoms is the positive end of the molecule.
Detailed explanation-5: -Polarity: Although the net charge of a water molecule is zero, water is polar because of its shape. The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other polar molecules.
