Answer;
C. Carbon forms strong, stable bonds with up to four other atoms, including other carbon atoms.
Step-by-step explanation;
- Carbon atoms can bond with many things and they have 4 valence electrons and they only need 4 more electrons to fill the outer shell. They also can form chains that are unlimited in length.
- The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds. Also its skeletons, can vary in length, branching and ring structure.
