The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...

He suggested that an atom was a tiny solid ball. He published his ideas in 1803. This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of ...

The structure of a small molecule can also be shown as a three-dimensional ball and stick model. These models show how the atoms and bonds are arranged in space. The diagram shows a ball and stick ...
