Nuclear Energy Test

How does the structure of an atom relate to nuclear energy?

• The nucleus contains protons and neutrons, which can be split or fused to release nuclear energy.

• Electrons in the atom's shell release nuclear energy when they move.

• The atomic structure determines the color of nuclear energy.

• Nuclear energy is produced by chemical reactions in the atom.

What are isotopes?

• Atoms with the same number of protons but different numbers of neutrons

• Atoms with different numbers of protons and neutrons

• Atoms with the same number of neutrons but different numbers of protons

• Atoms with the same number of protons and neutrons

The processes that result in nuclear energy being released are:

• Photosynthesis and respiration

• Fission and fusion

• Evaporation and condensation

• Conduction and convection

What is nuclear radiation and what is its impact?

• Nuclear radiation is energy released from unstable isotopes.

• Nuclear radiation is a type of sound wave with no impact on living things.

• Nuclear radiation is a form of visible light that helps plants grow.

• Nuclear radiation is a harmless gas released from the sun.

Radioactive dating is used to:

• Determine the age of rocks and fossils

• Measure temperature changes

• Calculate speed of light

• Identify types of radiation

Which of the following best describes the benefits and risks of nuclear energy?

• It provides large amounts of energy with low greenhouse gas emissions, but poses risks such as radioactive waste and accidents.

• It is a renewable energy source with no environmental risks.

• It is inexpensive to build and operate, with no safety concerns.

• It produces only small amounts of energy and is not widely used.

What happened to the uranium nucleus when it was bombarded with neutrons?

Name one application of the advancement in nuclear energy mentioned in the passage.

• Medicine, nuclear energy power plants, or nuclear bombs (any one is correct).

• Solar panels for household electricity.

• Wind turbines for generating power.

• Hydroelectric dams for water storage.
