Question

Explain The Formation Of The Hydrogen Molecules With A Diagram


Open in App
Solution

Formation of Hydrogen molecule:

  • Hydrogen has only one electron in its S orbital.
  • Hence, the electronic configuration of the hydrogen atom is 1s1.
  • During the formation of the H2 molecule, the 1s orbitals of two hydrogen atoms containing one unpaired electron with opposite spin overlap with each other along the internuclear axis.
  • Here, the overlap is called s-s overlap, and such type of axial overlap results in the formation of a σ-covalent bond, which can be shown as:

Thus, in the above-mentioned way the hydrogen molecule formation can be explained.
