Detailed explanation-1: -There is no overall charge to a water molecule, but there is a slight positive charge on each hydrogen atom and a slight negative charge on the oxygen atom.
Detailed explanation-2: -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-3: -Water is a Polar Covalent Molecule The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
Detailed explanation-4: -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.
Detailed explanation-5: -Explanation: Water (H2O) is a polar molecule because the electrons of the hydrogen atoms get “pulled” towards the electrons of the oxygen atom. This makes a region of positive charge on the hydrogen atoms and the negative charge on the other end of the molecule, which is the oxygen atom.
