What does fission mean?

• band of light frequencies emitted by a source, with dark lines where specific wavelengths of light have been absorbed

• specific frequencies of light emitted by the atoms of a particular element

• occurs when two smaller atomic nuclei combine to form a heavier, more stable nucleus.

• occurs when a heavy, unstable nucleus splits into two smaller nuclei.

Do the Nuclear fission take place in the Sun.

• No

• Yes

Answer explanation

Nuclear fission does not take place in the Sun. The Sun contains only lighter elements, such as hydrogen and helium. The Sun contains the correct fuel and conditions required for nuclear fusion.
