Water Molecule |
||||||
 |
||||||
|
||||||
| A water molecule consists of an oxygen atom and two hydrogen atoms, which are attached at an angle of 105°. Not shown are two pairs of electrons on the bottom that form a similar angle in a plane perpendicular to this view. This asymmetrical arrangement accounts for the many unusual properties of water, such as the fact that it expands when it freezes. | ||||||
