A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.

Answer:
The scientific models are the simplified visual representations of the complex processes or systems of the natural world.
The models serve many important purposes in scientific investigations as they are used by the researchers to test the predicted hypothesis proposed and to explain the results to another group of peoples which could be a layman.
The 3 D structures of molecules are represented by the globular models and stick key models which even represents the bonds between atoms.
Answer:
