What is the difference between the postulates given by K?ssel and Lewis and Langmuir and Lewis .. Give at least 5 differences in a tabular form (table manner) please don't send any link
Postulates of Kossel- Lewis electronic theory of valency:
1. According to this theory , atoms combine either by transfer of valence electrons from one atom to another or by sharing of valence electrons in order to acquire octet in its valence shell.
2. An ionic bond is formed by the transfer of electrons between two atoms. The atom which lose electron/s and the atom which gains electron/s can achieve octet in their valence shell.
3. A covalent bond is formed by sharing of electrons between the two atoms. Atoms can achieve octet in their valence shell by sharing one , two or three electrons from each atom.

The octet rule or the electronic theory of chemical bonding was developed by Kossel and Lewis. According to this rule, atoms can combine either by transfer of valence electrons from one atom to another or by sharing their valence electrons in order to attain the nearest noble gas configuration by having an octet in their valence shell.
Lewis–Langmuir theory. : A chemical theory of atomic structure: the atom consists of a positive nucleus surrounded by concentric cubic shells at the corners of which the electrons are located
