What makes something radioactive?

elements with an atomic number above 81

What is nuclear fission?

Big nucleus splits to small nuclei

Small nuclei fuse into a bigger nucleus

A benefit to using nuclear fission power is that it:

conserves organic fuels, like oil, coal, and wood

eliminates huge quantities of sulfur dioxides, which pollute our air

The half life of a radioactive substance:

increases then decreases with time

What is an advantage of nuclear energy?

it is the safest way to make energy

More and more countries are turning toward utilizing nuclear power plants to generate electricity, as the supply of fossil fuels continues to decrease. Which of the following is an advantage of using nuclear power instead of power generated from burning fossil fuels?

nuclear power plants generate less air pollution

nuclear power plants are easier to build and require fewer safety precautions

fossil fuels are at a higher risk for theft than nuclear fuels

accidents at fossil fuel plants are more catastrophic than those at a nuclear plant

In a fusion reaction, two atoms of hydrogen combine to form

1 atom of hydrogen and 1 atom of lithium.

What is one way in which fission differs from fusion?

Fission splits nuclei, fusion combines nuclei.

Fission deals with the nucleus, fusion pertains to the electrons.

Fission releases energy, fusion absorbs energy.

Fission is not a radioactive process, fusion is radioactive.

Which particles make up the nucleus of an atom?

electrons, protons, and neutrons
