Carbon does not form ionic compounds. Why?

(N/A) To form an ionic bond,carbon would either need to lose $4e^-$ to form a $C^{4+}$ ion or gain $4e^-$ to form a $C^{4-}$ ion.
$1$. Losing $4e^-$ requires a very large amount of energy to overcome the strong nuclear attraction,which is not energetically favorable.
$2$. Gaining $4e^-$ would result in $10e^-$ being held by only $6$ protons in the nucleus,which creates significant instability due to the difficulty of the nucleus in holding such a large number of electrons.
Therefore,carbon does not form ionic compounds and instead forms covalent bonds by sharing electrons.
