What are the four properties of water?
71% of the Earth is covered by water and 97% of this water is in the oceans. Water is made up of two atoms of hydrogen and one atom of oxygen. Because of water’s electronic structure, the oxygen atom has a slight negative charge on it and the hydrogen atoms are slightly positive. When water molecules are close together, their positive and negative regions are attracted. These attractive forces are known as hydrogen bonds. Hydrogen bonds are the reason for water’s very special properties which make life on Earth possible.
