How do the bonding properties of carbon atoms allow for the large variety of carbon-based molecules in living things? a. carbon atoms each form ions that bond with other ions, which allows carbon to form the organic molecules found in organisms. b. carbon atoms each form bonds with eight other atoms, which allows carbon to form the organic molecules found in organisms. c. carbon atoms each have four valence electrons, allowing carbon to bond with as many as four other atoms, including other carbon atoms. d. carbon atoms each have an unbalanced charge, allowing carbon to donate electrons to many different atoms, including other carbon atoms.
