WebMar 20, 2016 · The carbon atom has 4 valence electrons, and is most stable when it forms 4 covalent bonds with other atoms. Explanation: CH 4, H 3C −CH 3, H 2C = CH 2; in 2 of these examples, the 4 valence electrons on C are formally paired with the 1 electron on H to form form 4 covalent bonds. how is a theory formed
