Carbon has 4 valence electrons and requires 4 more electrons to complete its octet. However, gaining 4 electrons is energetically unfavorable because it would create a C⁴⁻ ion, which is highly unstable due to extreme negative charge repulsion. Instead, carbon forms covalent bonds by sharing electrons with other atoms.
