What are disadvantages of using the ball and stick models to construct molecules?

Ball and stick models can oversimplify molecular structures, potentially misrepresenting bond angles and lengths since they do not accurately depict the electron cloud or spatial arrangement of atoms. Additionally, these models can create a misleading sense of scale, as the relative sizes of atoms are not proportionately represented. They also fail to convey the dynamic nature of molecules, as they depict static structures rather than the flexibility and movement inherent in real molecular interactions.
