Nuclear Energy - Practice 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 atomic nuclei and can cause harmful effects on living organisms.

• 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.
