Trivia questions with answers about neutrons

What is a neutron?
A: The neutron is a subatomic particle, symbol n or n0, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.

Protons and neutrons constitute the nuclei of what?
A: Atoms.

Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as what?
A: Nucleons.

Their properties and interactions are described by what?
A: Nuclear physics.

Protons and neutrons are not elementary particles; each is composed of what?
A: Three quarks.


The chemical properties of an atom are mostly determined by what?
A: The configuration of electrons that orbit the atom's heavy nucleus.

The electron configuration is determined by the charge of the nucleus, which is determined by what?
A: The number of protons, or atomic number.

The number of neutrons is what?
A: The neutron number.

Neutrons do not affect the electron configuration, but the sum of atomic and neutron numbers is what?
A: The mass of the nucleus.

Atoms of a chemical element that differ only in neutron number are called what?
A: Isotopes.


Some elements occur in nature with only one stable isotope, such as what?
A: Fluorine.

Other elements occur with many stable isotopes, such as tin with what?
A: Ten stable isotopes, and some elements such as technetium have no stable isotope.

The properties of an atomic nucleus depend on what?
A: Both atomic and neutron numbers.

With their positive charge, the protons within the nucleus are repelled by what?
A: The long-range electromagnetic force.

The much stronger, but short-range, nuclear force does what?
A: Binds the nucleons closely together.


Neutrons are required for the stability of nuclei, with the exception of what?
A: The single-proton hydrogen nucleus.

Neutrons are produced copiously in what?
A: Nuclear fission and fusion.

They are a primary contributor to the nucleosynthesis of chemical elements within stars through what?
A: Fission, fusion, and neutron capture processes.

The neutron is essential to the production of what?
A: Nuclear power.

In the decade after the neutron was discovered by James Chadwick in 1932, neutrons were used to induce  what?
A:  Many different types of nuclear transmutations.


With the discovery of nuclear fission in 1938, it was quickly realized that, if a fission event produced neutrons, each of these neutrons might cause what?
A: Further fission events, in a cascade known as a nuclear chain reaction.

These events and findings led to the first what?
A: The first self-sustaining nuclear reactor (Chicago Pile-1, 1942) and the first nuclear weapon (Trinity, 1945).

Dedicated neutron sources like neutron generators, research reactors and spallation sources produce free neutrons for use what?
A In irradiation and in neutron scattering experiments.

A free neutron spontaneously decays to what?
A: A proton, an electron, and an antineutrino, with a mean lifetime of about 15 minutes.

Free neutrons do not directly ionize atoms, but they do indirectly cause  what?
A: Ionizing radiation, so they can be a biological hazard, depending on dose.

A small natural "neutron background" flux of free neutrons exists on Earth, caused by what?
A: Cosmic ray showers, and by the natural radioactivity of spontaneously fissionable elements in the Earth's crust.
