What is the ionization energy of chlorine and carbon?
Chlorine has a very high ionization energy of chlorine is 1251.2 kJ/mole while carbon has 1086.5 kJ/mole. Owing to the high ionization enthalpy of both elements it is easier to form a covalent bond between them.
What type of bond is a covalent bond?
Covalent Bonds. Elements with extremely high ionization energies can’t lose electrons, and those with extremely low electron affinity can’t accept them. Such elements’ atoms try to share electrons with atoms of other elements or with the same element’s atoms, resulting in an octet arrangement in both valence shells.

Why would an atom prefer a covalent bond?
As a result, the smaller an atom is , the closer it is to the nucleus. The electrons would be under strong molecular attraction making it difficult for them to leave the atom. So instead of completely transferring the electrons through an ionic bond, the atom would prefer a covalent bond via sharing of electrons.
How many electrons does carbon need to become stable?
Covalent Bonding in Carbon Atom. To become stable, Carbon’s electronic configuration needs it to gain or lose four electrons, which seems unlikely because: 1. Carbon can’t receive four electrons to turn into a carbon anion (C4-) because six protons cannot carry ten electrons, causing the atom to become unstable. 2.
