19 Extraordinary Facts About Valence Shell Electron Pair Repulsion (VSEPR)

VSEPR theory is a fundamental concept in chemistry.

The VSEPR theory, which stands for Valence Shell Electron Pair Repulsion, explains the arrangement of molecules based on the repulsion between electron pairs in the valence shell of atoms.

VSEPR theory was developed by Ronald Gillespie and Ronald Nyholm.

In the 1950s, chemists Ronald Gillespie and Ronald Nyholm independently proposed the VSEPR theory as a way to predict and understand the geometric shapes of molecules.

VSEPR theory helps in predicting molecular shapes.

By considering the number of electron pairs around the central atom and their repulsion, VSEPR theory allows us to determine the most stable arrangement and predict the shape of a molecule.

Electron pairs in VSEPR theory can be bonding or non-bonding.

VSEPR theory takes into account both the bonding electron pairs and non-bonding electron pairs around the central atom to determine the molecular geometry.

The electron pairs in VSEPR theory repel each other to minimize energy.

According to VSEPR theory, electron pairs try to stay as far apart from each other as possible in order to minimize electrostatic repulsion, resulting in specific molecular shapes.
