What is an advantage of nuclear energy?

it is the safest way to make energy

How do atoms with stable nuclei differ from atoms with unstable nuclei? Nuclei is the plural of nucleus.

The number of particles in stable nuclei never changes; the number of particles in unstable nuclei does change

Stable nuclei contain equal numbers of protons and neutrons; unstable nuclei do not

Stable nuclei emit electrons; unstable nuclei emit protons and neutrons

Stable nuclei can be found everywhere; unstable nuclei do not occur in nature

What happens in a chain reaction?

An isotope that releases several million times more energy per reaction than compared to a chemical reaction

An isotope that reacts to a nuclear explosion from an atomic bomb

Various isotopes exploding at all once

What happens to the nuclei of isotopes during a FISSION reaction ?

They break down or break a part

They fuse and/or combine together

They add more neutrons to its mass

They collapse into a black hole

What happens to the nuclei of isotopes during a FUSION reaction ?

They fuse and/or combine together

They break down or break a part

They add more neutrons to its mass

They collapse into a black hole

What is the function of the cooling towers of the nuclear reactor?

to limit the heat produced by the uranium

What is a chain reaction?

When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to split

When electrons are emitted causing electricity

When a nuclear fission reaction occurs, the protons emitted can strike other nuclei in the sample, and cause them to split

When a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to split

What do control rods do in a nuclear reactor?

Regulate the rate of reaction by absorbing and slowing neutrons

Produce neutrons to increase the rate of reaction

Reduce heat produced by the uranium rods

One disadvantage of nuclear energy is ___.

it leaves behind radioactive waste

it emits large amounts of pollution into the atmosphere

Which of the following is an example of nuclear fusion?

Two hydrogen atoms are combined to form a helium atom

A plutonium atom is used to start a chain reaction that detonates a nuclear weapon

A uranium atom is split apart into lighter elements

Two hydrogen atoms bond with an oxygen atom to form a water molecule

Identify elements A and B and the process, C, in the illustration below.

Deuterium, Tritium, Nuclear Fusion

Deuterium, Tritium, Nuclear Fission

Tritium, Hydrogen, Nuclear Fusion

Deuterium, Hydrogen, Nuclear Fission

Which of the following statements BEST describes nuclear fusion?

Nuclear fusion usually requires a high-temperature environment

Nuclear fusion is a common source of energy

Nuclear fusion usually requires freezing temperatures

Nuclear fusion releases a small amount of energy compared to most chemical reactions

Which of the following statements BEST describes nuclear fission?

Nuclear fission causes the reaction inside an atomic bomb

Nuclear fission inside stars can absorb or release energy

Nuclear fission is usually present in endothermic reactions

Nuclear fission cannot be used to produce power in nuclear energy plants

Which risk is associated with using nuclear fission to produce energy in a power plant?

exposure of workers to radiation

depletion of atmospheric oxygen

exposure of workers to sulfur dioxide

What is a problem commonly associated with nuclear power facilities?

It is difficult to dispose of wastes.

A small quantity of energy is produced.

Reaction products contribute to acid rain

It is impossible to control nuclear fission.

The main function of a coolant in a nuclear fission reactor is to

absorb energy produced by the reaction

slow down the speed of the neutrons

shield the wall of the reactor from radiation damage

adjust the number of neutrons available for reaction

The operation of a commercial nuclear reactor requires an isotope that will undergo

fission and a controlled chain reaction

fission and an uncontrolled chain reaction

fusion and a controlled chain reaction

fusion and an uncontrolled chain reaction

The purpose of the high-density concrete used in some nuclear reactors is to

shield the reactor personnel from radiation exposure

shield the reactor walls from radiation damage

control the rate of the nuclear reaction

control the speed of the neutrons

Which is a benefit of using nuclear power?

Makes us less reliant on fossil fuels

Exposes workers to hazards in nuclear facilities

Generates radioactive nuclear waste

Causes thermal pollution to water systems
