Which of these statements correctly describes how the chain reaction occurs in nuclear fission.

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

Uranium releases electrons to create electricity

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

Protons and neutrons change to electrons because the nuclei are so big

What is a benefit of nuclear fission?

The ability to release tremendous amounts of energy

The ability to produce more energy than nuclear fusion

There are no beneficial aspects of nuclear fission

One disadvantage of nuclear energy is ___.

it leaves behind radioactive waste

it emits large amounts of pollution into the atmosphere

Nuclear fusion releases energy when:

very light nuclei fuse together

uranium splits into two fragments

Energy in both fission and fusion comes from

the mass defect between reactants and products

The time it takes for half of any number of radioactive atoms to decay

The average time it takes for any element to disappear completely

The time it takes for a radioactive atom to lose half its neutrons

The time it takes for a radioactive atom to lose half its electrons

In a fission power station the chain reaction is controlled by

control rods which absorb neutrons

control rods which absorb electrons

control rods which absorb protons

control rods which absorb atoms

Uranium is the fuel used in a fission reaction through the process of

Stable U235 - becoming unstable U236 by means of bombardment by a neutron

Stable U236 - becoming unstable U235 by means of bombardment by an electron

Stable U236 - becoming unstable U235 by means of bombardment by a neutron

Stable U235 - becoming unstable U236 by means of bombardment by an electron

A spontaneous nuclear reaction is one where

the mass defect is positive, resulting in an exothermic reaction

the mass defect is positive, resulting in an endothermic reaction

the mass defect is negative, resulting in an exothermic reaction

the mass defect is negative, resulting in an endothermic reaction
