Why is water considered a polar molecule?
The negatively charged oxygen atom attracts the positively charged hydrogen atoms. |
The oxygen is found between the two hydrogens. |
It remains liquid even at very low temperatures. |
Both hydrogens are at one end of the molecule, and oxygen is at the other end. |
Its electrons spend more time with its oxygen than with either hydrogen. |
