electron geometry

Electron geometry describes the three-dimensional arrangement of all electron pairs—bonding and non-bonding—around a central atom in a molecule. These pairs repel each other, shaping the molecule's overall structure. Understanding electron geometry helps predict the molecule's shape, bonding angles, and reactivity. For example, if there are four pairs of electrons around a central atom arranged evenly, the electron geometry is tetrahedral. This concept is foundational in chemistry for understanding molecular shapes and behaviors, as the positions of electron pairs influence how molecules interact and function.
