What makes molecules polar: an uneven distribution of electrons between the oxygen and hydrogen atoms.
- So, a water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
- Water has a neutral charge.
- Because of their partial positive and negative charges, polar molecules, such as water, attract each other like magnets.
- The attraction between a hydrogen atom with a partial negative charge and another atom with a partial positive charge is called a hydrogen bond.
- Because water is a polar molecule, it is able to form multiple hydrogen bonds, which is why water has many special properties (hydrogen bonds are the strongest bonds that can form between molecules).
Hope this helps!
