What model shows how carbon atoms connect?

The model that shows how carbon atoms connect is the Lewis structure, which illustrates the arrangement of electrons around atoms, including bonding pairs and lone pairs. Additionally, the Valence Shell Electron Pair Repulsion (VSEPR) model helps predict the three-dimensional shapes of molecules formed by carbon atoms. For more complex structures, the molecular orbital theory can also be applied to describe the bonding and interactions of carbon atoms in molecules.
