Recall that the octet rule states that atoms tend to form bonds until they are surrounded by eight electrons in their valence shell.
Determine the number of valence electrons in a neutral carbon atom. Carbon is in group 14 of the periodic table, so it has 4 valence electrons.
Since carbon has 4 valence electrons, it needs 4 more electrons to complete its octet (reach 8 electrons in total).
Each covalent bond involves sharing one pair of electrons (2 electrons), so carbon can form enough bonds to share 4 additional electrons.
Therefore, a neutral carbon atom typically forms 4 covalent bonds to satisfy the octet rule.
