The best arrangement of balls to model a structure typically depends on the specific characteristics of that structure. For example, if you're modeling a crystalline solid, a close-packed arrangement like face-centered cubic (FCC) or hexagonal close-packed (HCP) would be ideal. Alternatively, for a molecular structure like a benzene ring, a planar arrangement with equal spacing between the balls (representing atoms) would be more suitable. The choice of arrangement should reflect the spatial and bonding properties of the structure being modeled.
In a face-centered cubic (FCC) structure, the best model for this arrangement is to represent the atoms as spheres arranged at the corners and the centers of each face of the cube. Each corner atom is shared by eight adjacent cubes, while each face-centered atom is shared by two cubes. This arrangement allows each atom to have twelve equidistant neighboring atoms, corresponding to the FCC's coordination number. The close packing of these spheres maximizes space efficiency and stability in the structure.
A ball-and-stick model or a space-filling model best represent a molecule's three-dimensional shape, as they show the spatial arrangement of atoms and their relative sizes. These models provide a clearer visualization of the molecule's structure and how atoms are connected in 3D space.
Fluid Mosaic Model
That is an example of a molecular model, a visual representation that helps illustrate the structure and composition of molecules in a simplified way. These models are commonly used in chemistry to provide insights into the arrangement of atoms within a molecule.
To make a model of H2O, you can use small balls or beads to represent the atoms. Two smaller balls can be used for hydrogen atoms and one larger ball for the oxygen atom, connecting them with thin sticks or toothpicks to represent the bonds between them. This helps visualize the molecular structure of water.

If you use balls to explain the structure of a molecule you have made a model.
The model developed by scientists to describe the arrangement of molecules within a structure is called a molecular model or molecular structure model. These models help visualize the spatial arrangement of atoms and bonds within a molecule, providing valuable insights into its properties and behavior.

Ball-and-Stick Model
Atoms are imagined as tiny balls in the billiard ball model or Dalton's atomic theory. This model suggests that atoms are indivisible, solid particles with no internal structure.
Fluid Mosaic Model
The model is called the fluid mosaic model. It describes the structure of cell membranes as a fluid lipid bilayer with embedded proteins that move freely within the membrane.

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.
The three subatomic models are the plum pudding model, the nuclear model, and the current model known as the quantum mechanical model. These models describe the structure of the atom and the arrangement of subatomic particles within it.
A model that illustrates the arrangement of electrons in an atom is the Bohr model or the quantum mechanical model. These models depict the distribution of electrons in different energy levels or orbitals around the nucleus of an atom. Each model helps visualize the structure of an atom and how electrons occupy specific regions around the nucleus based on their energy.
