Question

The theory developed by Kossel and Lewis are called :

• A. valence bond theory
• B. electronic theory of valence
• C. ligand field theory
• D. none of the above

Answer 1

Answer: (B)

electronic theory of valence

Lewis theory revolves around the importance of valence electrons in chemical bonding. These are the electrons that are in the outermost shell.The bonding of an element is based on how they fill their octets i.e. achieve a noble gas electron configurations.Two ways are explicitly defined how electrons are used to form bonds. These are ionic (complete transfer of electron) and covalent (sharing of electrons) bonding.
