Answer: Water is a polar molecule since it has an unequal sharing of electrons. Water is chemically written as H2O meaning it consists of hydrogen and oxygen atoms. Hydrogen is number one in the Periodic Table whereas oxygen is number 14. As a result, the configuration of oxygen is 2.8.4 while that of hydrogen is 1. When two hydrogen atoms combine with one oxygen atom, two out of the four electrons in oxygen form the strong bond in water. The resulting effect is that there is an unequal sharing of electrons since two electrons remain unused. The hydrogen end becomes partially positive while the oxygen end is partially negative. Furthermore, the oxygen atom has a stronger attractive force hence drawing more atoms to it. Subsequently, there arises a charge imbalance within the molecule. Besides water, hydrogen fluoride is also a polar molecule.
