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 molecular model of water, illustrating its atomic structure where two hydrogen (H) atoms are covalently bonded to one oxygen (O) atom, resulting in the chemical formula H₂O. The blue balls represent the hydrogen atoms, while the green ball represents the oxygen atom, indicating the bent geometry of the water molecule.
