The polarity and components of water
Water is a “polar” molecule, that is, there is an irregular distribution of electron density in it. For this reason, water has a negative partial charge near the oxygen atom and a positive partial charge near the hydrogen atoms.
Water is a “polar” molecule, that is, there is an irregular distribution of electron density in it. For this reason, water has a negative partial charge near the oxygen atom and a positive partial charge near the hydrogen atoms.
The phenomenon of partial charges within the molecule is called polarity and the molecules that present this distribution of their electrical charge are known as dipoles.

The water molecule has a total of 10 protons and 10 electrons (8 from the oxygen atom and 1 from each of the two hydrogen atoms). Since these two electric charges compensate and make the molecule globally uncharged.

Here is an experiment about the polarity of water:
