An atom defined by its proton number, nucleon number and energy state. Thus it is not only clearly identified as a particular isotope of that atom but also its energy state is clearly defined. Particle Accelerator A particle accelerator is a device used to project charged particles at high speed into matter. Electric and magnetic fields are used to provide the forces to accelerate and control these charged particles at speeds approaching the speed of light. When these charged particles strike the nucleus of an atom, they alter its stability and new particles may be produced.Various devices used to detect subatomic particles are the Geiger counter, ionization chamber, bubble chamber, cloud chamber, spark chamber, scintillation counter, and photographic film.
A type of nucleus with a fixed number of protons and neutrons. The term nuclide is usually used to distinguish nuclear species of different chemical elements (i.e., those having different numbers of protons and neutrons), such as iodine 127 and uranium 235.
A term used to specify a type of nuclei or atoms with reference to its nuclear properties. A nuclide is often represented by the symbol AZX, or X - A where A is the mass number equal to the numbers of protons plus the number of neutrons in the nucleus, Z is the atomic number equal to the number of protons in the nucleus, X is the chemical symbol of the atom.
a general term applicable to all atomic forms of an element. Nuclides are characterized by the number of protons and neutrons in the nucleus, as well as by the amount of energy contained within the atom.
An atom or a collection of atoms whose nuclei have a specified number of protons and neutrons. Isotope is often (incorrectly) used for the term nuclide. The term nuclide was originally proposed by T.P. Kohman in 1947. Related to isobar. Related to isomer. Related to isotone. Related to isotope.
An individual atom of given atomic number Z and mass number A, for example, 92U235. A nuclide is any species of atom that exist for a measurable length of time and has a nuclear structure distinct from that of any other species of atom.
