Question

Explain Kossel - Lewis approach to chemical bonding

Answer 1

Answer:

Gilbert Newton Lewis postulated that atoms achieve the stable octet when they are linked by chemical bond. Basically Lewis explained the formation of covalent bond and Walther Kossel explained electrovalent bond.

Hope it helps ❤

Answer 2

1) Lewis explained covalent bond formation and kossel kossel explained ionic bond formation

2) Lewis pictured atom in terms of A positively charged kernel ( kernel consists of nucleus and inner electrons )

3) The valence shell can accommodate 8 electrons. this Octet electrons represent a stable electronic arrangement

4) Thus to attain stability atoms prefer to have eight electrons in their outermost shell this is called octet rule

5) atoms attain octet by losing, gaining or sharing electrons between two atoms forming chemical bonds

6) Elements of zero group are chemically inert and stable as they have octet configuration
