The source of energy produced by the sun is the

• burning of fossil fuel.

• fission of uranium.

• fusion of hydrogen.

• none of the choices

Nuclear fission is a reaction during which the

• nucleus of an atom is fused with another nucleus.

• nucleus of an atom is stimulated to split into fragments by some source.

• nucleus of an atom loses a proton with the release of energy.

• nucleus of an atom spontaneously splits into fragments.

In nuclear fusion

• large unstable nuclei are fused and then split.

• large unstable nuclei are split, releasing energy.

• small, relatively stable nuclei are fused together to create a larger atom.

• small, relatively stable nuclei are split, releasing energy.

A nuclear reaction occurs when the atom is

• ready to give away electrons

• stable

• in need of electrons

• unstable
