Chapter 22 Test 2017

What are atoms of the same element with different atomic masses called?

• Isotopes.

• Isobars.

• Isotones.

• Isomers.

Which type of reaction is primarily used in nuclear reactors to produce energy?

• Fusion reactions

• Fission reactions

• Chemical reactions

• Hydro-powered reactions

When an unstable isotope gives off a kind of radioactive decay known as an alpha particle, it is giving off:

• an electron.

• two protons and two neutrons.

• high energy electromagnetic radiation.

• a hydrogen atom.

The nuclear decay in which the only emission from the nucleus is pure energy is:

• alpha decay.

• beta decay.

• gamma decay.

• All of the above.

The force that holds neutrons and protons together in the nucleus is known as:

• the electronegative force.

• hydrogen bonding.

• the strong nuclear force.

• the weak nuclear force.

The particles involved in a nuclear reaction include:

• protons.

• electrons.

• neutrons.

• protons and neutrons

The function of the strong nuclear force is to overcome:

• the repulsive force between protons and electrons in an atom.

• the attractive force between protons and electrons in an atom.

• the attractive force between protons in the nucleus of an atom.

• the repulsive force between protons in the nucleus of an atom.

The process of combining nuclei of atoms to make different atoms is considered a:

• fission reaction.

• chemical reaction.

• fusion reaction.

• All of the above

Which type of reaction can occur in a particle accelerator?

• fission reaction

• chemical reaction

• radiation reactions

• All of the above

To protect your body from ALL types of radiation would require:

• a sheet of notebook paper.

• your clothing.

• a half-inch sheet of plywood.

• thick concrete walls.
