Neutron

An uncharged elementary particle found in the nucleus of every atom except hydrogen. Solitary mobile neutrons travelling at various speeds originate from fission reactions. Slow (thermal) neutrons can in turn readily cause fission in nuclei of 'fissile' isotopes, e.g. U-235, Pu-239, U-233; and fast neutrons can cause fission in nuclei of 'fertile' … ...

Neutron

One of the three fundamental particles which form atoms, the neutron has the mass of a proton but no electrical charge. Neutrons are emitted when large atomic nuclei are bombarded with alpha particles.

Neutron

One of the basic particles which make up an atom. A neutron and a proton have about the same weight, but the neutron has no electrical charge. In our diagrams, a neutron is represented by this:

Neutron

Why atomic weights are complicated. Each element has a certain number of protons in its nucleus, which defins what element it is (e.g,, 92 for Uranium, 2 for Helium, 109 for Meitnerium). To keep the positively charged protons from flying apart through electrostatic repulsion, they are bound together by the 'strong force' which is a veyr powerful fo...

Neutron

The neutron is a constituent of the Nucleus of an Atom and has an Atomic Mass unit of 1 (identical mass to a Proton ). Unlike protons, the neutron does not carry an electrical charge. Its electrical neutrality allows it to take part in many types of nuclear reactions because it is not deflected by the positive charge of the protons. Neutrons are no...
