The oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of

• positive electrons

• molecules

• polarity

• unshared electrons

All of the electron pairs—shared and unshared—of the molecule

• repel each other

• attract each other

The plus end of one—a hydrogen atom—associates with the minus end of another—an oxygen atom.

These attractions are an example of

• oxygen bonds

• hydrogen bonds

• solvent bonds

• positive bonds

The unequal sharing of electrons between atoms

• Polar covalent bond

• Covalent polar bond

• Dipolar bond

• Lewis bond

The unequal sharing of electrons, in which the centre of positive charge and the centre of negative charge are not the same

• Dipol

• Polar

• Configuration

• Bond
