We use models to show atoms because they help visualize and simplify the complex and abstract nature of atomic structure. Atomic models, such as the Bohr model or quantum mechanical models, provide a way to represent the arrangement of electrons, protons, and neutrons, making it easier to understand chemical behavior and interactions. These models allow scientists to make predictions about the properties of elements and compounds, facilitating advancements in chemistry and related fields.
the use of models helps people dicuss the theory of how and why atoms form bonds
A ball-and-stick model or a space-filling model can show the geometry of a hydrocarbon molecule. Ball-and-stick models represent the atoms as balls and the bonds between them as sticks, while space-filling models show the molecule as if solid and filled the space the atoms occupy. Both models can provide a visual representation of the molecular geometry of hydrocarbons.

study their electronic configurations and how they overlap to form chemical bonds. This can be done through computational simulations or experimental techniques such as X-ray crystallography or spectroscopy. By understanding the interaction of their electrons, we can predict how the atoms will behave in different chemical reactions.
A long-peg in a molecular model set typically represents a single bond between two atoms. It is used to show the covalent bond where two atoms share a pair of electrons.
A molecular model, such as a ball-and-stick model or space-filling model, can show how carbon atoms are connected in a molecule. These models depict the arrangement of atoms and bonds in a three-dimensional representation.

One model that shows how atoms are arranged in a molecule is the ball-and-stick model. In this model, atoms are depicted as balls and bonds between them as sticks. This provides a visual representation of the spatial arrangement of atoms within a molecule.

To draw a model of H2O, you can represent it using ball-and-stick models or space-filling models. In a ball-and-stick model, you can use two small balls to represent the hydrogen atoms and one larger ball to represent the oxygen atom, connected by sticks to show the bonds. In a space-filling model, the atoms are represented by spheres whose sizes reflect their van der Waals radius, showing how they pack together in space.

A calotte model is a space-filling model - a three-dimensional molecular model where the atoms are represented by spheres whose radii are proportional to the radii of the atoms.
