Strong chemical bonding is due to the sharing or transfer of electrons between the atoms involved. The strength of a chemical bond varies from strong or primary bonds and weak or secondary bonds. Chemical bonds can result from three types of interactions between atoms: Sometimes, atoms of particular elements easily bond with different atoms to form molecules. It is based on the assumption that the molecule will take such a shape that will minimize electronic repulsion in the valence shell of that atom.Ītoms come together to form molecules and molecules come together and bind by chemical bonds to form elements or compounds. The theory was given by Sidgwick and Powell in the year 1940. The VSEPR theory is a tool that is used for predicting the shape of a molecule from the electron pairs that surround the central atoms of that molecule. VSEPR theory suggests that the repulsion between two electrons is caused by the Pauli exclusion principle that has greater importance than electrostatic repulsion in the determination of a molecule's geometry. This theory is also known as the Gillespie-Nyholm theory to honor Ronald Nyholm and Ronald Gillespie who laid its foundation. This arrangement of the atom shapes the geometry of the resulting molecule. The VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) is based on the fact that there is a repulsion between the pairs of valence electrons in all the atoms, and the atoms will always try to arrange themselves in a manner in which the electron pair repulsion is minimized.
