Ice. Image 1 of 3. Artwork of the hexagonal crystal structure of solid water (ice). The atoms are shown as balls here,and are colour coded: oxygen (red) and hydrogen (yellow). Water has the formula H2O. Each oxygen atom is bonded to two hydrogen atoms. The oxygen atom has a slight negative charge,and the hydrogen atoms have small positive ones. This means a hydrogen from a neighbouring water molecule can form a weak bond known as a hydrogen bond to an adjacent oxygen. This leads to the rigid crystal structure of ice. For water as a liquid and as it evaporates,see images A504/088 and A504/089 respectively | |
