answered-by-expert Expert Answer

Covalent Bond:

The chemical bond formed due to mutual sharing of electrons between the given pairs of atoms of non-metallic elements.

      Conditions for Formation of Covalent Compounds

  • Both atoms should have high electronegativity, electron affinity and ionisation energy.
  • The electronegative difference between the two combining atoms should be negligible.
  • Both atoms should have four or more electrons in their outermost shell.

Atom

Electronic configuration

Nearest noble gas

To attain the stable electronic configuration of the nearest noble gas

Hydrogen

11H  [1]

Helium [2]

Hydrogen needs one electron to complete the duplet.

Oxygen

 168O  [2,6]

Neon [2,8]

Oxygen needs two electrons to complete the octet.
