  1. Neutron

    The neutron is a subatomic hadron particle which has the symbol n or n0, no net electric charge and a mass slightly larger than that of a proton. With the exception of hydrogen-1, nuclei of atoms consist of protons and neutrons, which are therefore collectively referred to as nucleons. The number of protons in a nucleus is the atomic number and defines the type of element the atom forms. Neutrons are necessary within an atomic nucleus as they bind with protons via the nuclear force; protons are unable to bind with each other because their mutual electromagnetic repulsion is stronger than the attraction of the nuclear force. The number of neutrons is the neutron number and determines the isotope of an element. For example, the abundant carbon-12 isotope has 6 protons and 6 neutrons, while the very rare radioactive carbon-14 isotope has 6 protons and 8 neutrons. While bound neutrons in nuclei are stable, free neutrons are unstable; they undergo beta decay with a mean lifetime of just under 15 minutes. Free neutrons are produced in nuclear fission and fusion. Dedicated neutron sources like neutron generators, research reactors and spallation sources produce free neutrons for use in irradiation and in neutron scattering experiments. Even though it is not a chemical element, the free neutron is sometimes included in tables of nuclides.

Examples of neutron in a Sentence

  1. Northwesterns Raffaella Margutti:

    We think that The Cow is the formation of an accreting black hole or neutron star, we know from theory that black holes and neutron stars form when a star dies, but weve never seen them right after they are born. Never.

  2. Sharon Morsink:

    In that work, we have to assume that Einsteins theory of gravity is correct, since the data analysis is already very complex, so tests of Einsteins gravity using neutron stars really make me feel better about our assumption that Einsteins theory describes the gravity of a neutron star correctly!

  3. Szabolcs Marka:

    And when we hear the universe, we will learn about the secret life of black holes -- their birth, their death, their marriage, their feeding. We will hear when a black hole eats a neutron star, nobody has 'seen' that before. We will not only understand it, we will 'see' it. It's the most fascinating thing I can imagine.

  4. Susan Scott:

    We have always thought that there should be binary systems of a black hole and a neutron star circling each other out in space, so if this event is confirmed, it would be the first evidence that such systems do actually exist, and that some of them are spiraling closer and closer and eventually smashing together.

  5. Sharon Morsink:

    At some level, the majority of physicists believe that Einsteins theory of gravity, called general relativity, is correct. However, that belief is mainly based on observations of phenomena taking place in regions of space with weak gravity, while Einsteins theory of gravity is meant to explain phenomena taking place near really strong gravitational fields, neutron stars and black holes are the objects that have the strongest known gravitational fields, so any test of gravity that involves these objects really test the heart of Einsteins gravity theory.
