What is the Molecular Geometry Calculator?

The Molecular Geometry Calculator helps determine the 3D shape of a molecule based on the number of bonding pairs and lone pairs around a central atom. By entering the number of bonding and lone electron pairs, this tool predicts the molecular geometry using standard VSEPR (Valence Shell Electron Pair Repulsion) rules. It provides an instant result, helping students, chemists, and enthusiasts visualize molecular structures, plan experiments, or understand chemical bonding concepts.

How to Use:

1. Enter Number of Bonding Pairs: Type the total bonding pairs (shared electron pairs) connected to the central atom.
2. Enter Number of Lone Pairs: Input the number of lone (non-bonding) electron pairs on the central atom.
3. Click “Calculate”: The calculator evaluates the total electron pairs and determines the molecular geometry.
4. Review the Result: The result displays the predicted geometry, such as Linear, Tetrahedral, Bent, Trigonal Pyramidal, or Octahedral, helping you understand the molecule’s shape and bonding arrangement.
