The Molecular Geometry Calculator allows you to determine the shape of a molecule based on the number of sigma bonds and lone pairs around the central atom. By entering these values, the tool calculates the molecular geometry following the VSEPR theory, helping you identify structures such as linear, bent, trigonal planar, tetrahedral, trigonal pyramidal, and more. This calculator is useful for chemistry students and educators to easily visualize molecular shapes and understand chemical bonding patterns.
