Carbon forms different types of bonds using the four electrons in a. its outermost energy level. b. its innermost energy level. c. its lowest energy level. d. its nuclear energy level.

B. Its innermost energy level.

Explanation:

Carbon has six electrons, four of which are located in its valence shell. Thus, the tetravalent carbon makes four covalent bonds to achieve its chemical stability. These connections are made at your innermost energy level.

It can bond with other carbon atoms, chaining together, to form numerous types of chains. The carbon atom binds to hydrogen and other common elements in organic compounds such as oxygen (O), nitrogen (N), sulfur (S), halogens (Cl, Br, F, I), etc.
