• Atomic number -6
  • Electronic configuration –



Carbon cannot form the ionic bond because :

  • One of the possibilities is to attain four electrons and form C4– anion. But it will be difficult for the nucleus to hold four more electrons firmly.
  • Another possibility is to lose four electrons forming C4+ cation. But this will also be difficult due to the requirement of large energy to lose four electrons from the outermost shell. As a result the atom will contain six protons and two electrons.
  • Carbon attains the noble gas configuration by sharing its valence electrons with other atoms.Such mutual sharing of electrons between atoms to attain a stable noble gas configuration is called Covalent bonding.
