The compound is made up of the two different elements: hydrogen and oxygen. Water has a formula of H2O. Two hydrogen atoms are combined with an oxygen atom by sharing electrons via a process called covalent bonding.
It is polarised and the molecules form weak hydrogen bonds between them selves
Although it is a simple compound it has a complex set of properties. It has been argued that nearly everything about water is somehow unusual or contradictory.
For example, liquid water contracts when cooled until it reaches a temperature of around 4C. This is the temperature where it reaches its maximum density...
