Question

A model shows a molecule of water. The model shows two small blue balls attached to a larger green ball with one stick attaching each blue ball. A legend shows that the blue balls are H and the green ball is O. A chemical formula shows H2O.

In one to two sentences, identify the type of model shown and describe the atomic structure of a molecule of water.

Answer 1

The model shown is a ball-and-stick model, where the blue balls represent hydrogen atoms (H) and the green ball represents an oxygen atom (O). The sticks represent the chemical bonds between the atoms, with each hydrogen atom attached to the oxygen atom.
