How is vbt different from lewis concept
WebAccording to the concept of the Kossel-Lewis approach, the atom related to different elements took active participation in combination to complete their octet (8 electrons in the outermost valence shell) or duplet ( 2 valence electrons in the outer valence shell )for attaining the nearest noble gas configuration. WebVerified by Toppr. (i) According to Lewis concept, a covalent bond is formed by mutual sharing of electrons whereas according to VB theory a covalent bond is formed by …

WebAlthough the Lewis structure and molecular orbital models of oxygen yield the same bond order, there is an important difference between these models. The electrons in the Lewis structure are all paired, but there are two unpaired electrons in the molecular orbital description of the molecule. Web12 nov. 2016 · DIFFERENCES Valence bond theory assumes that electrons in a molecule are simply the electrons in the original atomic orbitals, with some used while bonding. In other words, it does not account for the true distribution of electrons within molecules as molecules, but instead, treats electrons as if they are "localized" on the atoms …
