molecular geometry

**molecular geometry**

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule. It determines the shape and spatial orientation of the molecule, which influences its physical and chemical properties, such as polarity, reactivity, and biological activity. Understanding molecular geometry is essential in fields like chemistry, biochemistry, and materials science, as it helps predict molecular behavior and interactions. Common molecular shapes include linear, bent, tetrahedral, trigonal planar, and octahedral, each defined by the positions of atoms and electron pairs around a central atom.
