Elements forming ionic compounds attain noble gas electronic configuration by either gaining or losing electrons from their valence shells. Explain giving reason why carbon cannot attains such a configuration in this manner to from its compounds. Name the type of bonds formed in ionic compounds and in the compound formed by carbon. also explain with reason why carbon compounds are generally poor conductors of electricity.

Carbon has 4 electrons in its outermost shell. It cannot lose 4 electrons to form c4+ because very high energy is required to remove 4 electrons.
It cannot gain 4 electrons to form c4- ions because it is difficult for 6 protons to hold on to 10 electrons.
Ionic/ Electrovalent bonds.
Covalent bonds
There are no charged particles in carbon compounds and hence poor conductor of electricity.
