Why does carbon form covalent rather than ionic bonds?
AIt is too heavy for ions
BIt can share four electrons to fill its octet
CIt does not have valence electrons
DIts nucleus is too small
Answer & Solution
Correct answer: B. It can share four electrons to fill its octet
1. Forming C⁴⁺ or C⁴⁻ would need very large amounts of energy.
2. Carbon instead shares its four valence electrons with other atoms.
3. Sharing fills the outer shell up to eight electrons.
4. So carbon makes covalent bonds rather than ions.
