What does VSPER theory state?

VSEPR theory, or Valence Shell Electron Pair Repulsion theory, states that the geometry of a molecule is determined by the repulsion between electron pairs surrounding a central atom. According to this theory, electron pairs (both bonding and non-bonding) will arrange themselves as far apart as possible to minimize repulsion, resulting in specific molecular shapes. This helps predict the three-dimensional structure of molecules based on the number of electron pairs and their arrangement around the central atom.
