Explanation:
In this case, you are missing the picture. Luckily I found one on another site, so I hope is the one you are asking for. If not, please post again with the picture.
According to the picture below, you need to write a chemical formula for each molecular model.
To do this, is just simple. Let's see each model per separate.
In the first model, we have a blue ball and three white balls. According to the nomenclature of the question a blue ball represents nitrogen atoms and white ball represents hydrogen, therefore, we have an atom of nitrogen bonded to three atoms of hydrogens, so, the chemical formula should be:
NH₃: This molecule corresponds to the Ammonia molecule.
The second picture, shows 4 black balls (representing an atom of carbon each) and each black ball holds a determinated number of white balls. The two of the middle have two white balls each, and the terminals have 3 white balls, therefore, the molecule should be the following:
CH₃ - CH₂ - CH₂ - CH₃: this corresponds to the butane
Finally, the last picture shows a yellow ball (which represents sulphur) and three red balls (representing oxygen each), so, the molecule that represents this would be:
SO₃: this is the sulfite ion.
