molecular geometry

Molecular geometry describes the three-dimensional arrangement of atoms within a molecule, which influences how it behaves and interacts with other molecules. Think of atoms as points connected by bonds, and the shape depends on how these bonds are arranged to minimize electron repulsion. Common shapes include linear, bent, trigonal planar, tetrahedral, and others, each with specific bond angles and structures. Understanding molecular geometry helps predict properties like reactivity, phase, and biological activity, playing a key role in chemistry, medicine, and materials science.
