The structure of ice and snow Ice consists of water molecules, H2O. Their structure in ice is essentially the same as in any other form of water. It is very important to notice that water molecules are bent 104 degrees. The electric field around the oxygen atom is stronger than that around the hydrogen. The electrons from the hydrogen atoms are drawn close to the oxygen. This leaves the hydrogen atoms positively charged. The connection between the oxygen and the hydrogen is known as a covalent bond. This kind of molecule is called a 'polar' molecule. The electrons near the oxygen arrange themselves so as to stay as far away from one another as possible. This minimises their mutual electric repulsion and leaves the molecule bent. In ice, oxygen atoms are "linked" to each other by the combination of a covalent bond and a hydrogen bond. A hydrogen bond is simply the...
