What a space-filling model of a compound?

A space-filling model of a compound visually represents the three-dimensional arrangement of atoms within a molecule. In this model, atoms are depicted as spheres that are scaled to their actual sizes, illustrating how they occupy space and interact with one another. This approach helps to convey the compound's geometric structure and spatial relationships, making it easier to understand molecular interactions and properties. Space-filling models are often used in chemistry and molecular Biology to visualize complex structures more intuitively.
