Models are used to show the arrangement of the atoms in a molecule.
Scientists test ideas about chemical evolution by using computer models.
There are three types of Chemical Formulas, which describe a chemical reaction. The first type of Chemical formula is called the Molecular Formula, which gives the number of each type of atom in a molecule.
Ball and Stick Models; In ball and stick models, the atoms are wooden of plastic balls with holes in them. Sticks or springs are used to represent chemical bonds. Each types of atom is represented by a specific color. and Space Filling Models; In this model, atoms are represented by truncated balls held together by snap fasteners so that the bonds are not visible. The balls are proportional in size to atoms.
To make them easier to understand. To make it possible to visualize the atoms and understand what they're actually doing. It helps to understand how they interact with each other and how they interact with other things.

Having high cheekbones are one of the most desirable qualities in a fashion/runway model. The modeling industry wants models that have strong bone structure because it photographs well, stands out in emphasizing a model's face in runway shows and sets them apart from other types of models.

Atomic models tell us about the structure of an atom which is based on what we know about how atoms behave. But it is not necessary that it will be a genuine picture of the structure of an atom.

Some topics you can study using models are Volcanoes, Earth's Structure, and the Solar System.
valence electrons
The purpose of using molecular models is to be able to see the three dimensional and geometric shape of the molecule or compound being modeled.
This is the water molecule.

Crick and Watson tried to understand the structure of DNA by building three dimensional models of the molecule.
