Introduction of Chemical Bonding

The attractive force which holds various constituents together in different chemical species is called a chemical bond.There are various mode of chemical combination.

  1. By the complete transfer of one or more electrons e.g ionic bond.
  2. when the share electrons are contributed by the two combining atoms equally. e.g covalent bond.
  3. when these electrons are contributed entirely by one one of the atoms but shared by both. e.g Co- ordinate covalent bond.

Kossel Lewis Approach

W. Kossel and G.N Lewis in 1916 .

“According to octet, atoms of various elements enter into chemical combination so as to attain the configuration of eight electrons in their outermost shell.”
