One advantage of conventional nuclear power, when compared to coal, is
a. no related occupational deaths.
b. limited risk from catastrophic accidents.
c. no contribution to global warming.
d. unlimited supply of raw materials.

Nuclear power is produced through nuclear reactions like fission. This is when radioactive elements, like Uranium, shed subparticles yielding another element like Polonium. Unlike coal, they do not emit greenhouse gases that contribute to global warming. Some risks are still there such as death from prolonged exposure to radioactive wastes and unprecedented extent of reactions. Supply of radioactive elements are also limited.

The answe ris letter C.

It won't lose or gain electrons if it's a covalent bond it shares the electrons with another atom or atoms. if it is an ionic bond it will lose the 3 electrons on the outer shell and become a positively charged ion.  credit goes to @sunshinebaby of answers.yahoo.com.
