Which of the following statements describes a covalent bond between Carbon and Hydrogen:

#Section 2: General Biology

  1. The electrons are shared equally between the two atoms of the bond.

  2. The electrons of the bond are pulled closer to the nucleus of Hydrogen, because its outer shell electron is closer to its nucleus than the outer shell electrons of Carbon are to its nucleus.

  3. The electrons of the bond are pulled closer to the nucleus of Hydrogen, because its nucleus contains more protons than Carbon.

  4. The electrons of the bond are pulled slightly closer to the nucleus of Carbon, because although its outer shell electrons are located farther away from the protons of its nucleus, it contains more protons than Hydrogen.
