A single isotope.
Compare with atomic nucleus and nuclide symbol. An atom or ion with a specified mass number and atomic number. For example, uranium-235 and carbon-14 are nuclides.
a specific isotope of an atom
nucleus containing a specific number of protons and a specific number of neutrons. (see isotope)
3/4 A species of atom characterized by its mass number, atomic number and nuclear energy state, provided that the mean life in that state is long enough to be observable.
an atomic nucleus with a specific energy state and specific number of protons and neutrons
an atom containing a specific number of protons (Z) and neutrons (N), e.g., 56Fe contains 26 protons and 30 neutrons
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 general term applicable to the isotopes of all elements, including both stable and radioactive forms ( radionuclides).
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.
an atom described by its atomic number (Z) and its mass number (A)
a particular type of atomic nucleus, or more generally an agglomeration of protons and neutrons
a species of atom characterized by its number of protons and neutrons and the energy content of its nucleus
a species of atom having a specified numbers of neutrons and protons in its nucleus
An atomic nucleus specified by atomic weight, atomic number, and energy state; a radionuclide is a radioactive nuclide.
A particular nuclear species characterized by a specific atomic number and mass number.
A general term referring to all isotopes of an element.
An of atom characterized by its mass number, atomic number, and energy state of its nucleus.
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.
Any atom that exists for a measurable length of time. A nuclide can be identified by its atomic weight, atomic number, and energy state.
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.
A species of atom characterized by the constitution of its nucleus and hence by the number of protons, the number of neutrons, and the energy content.
An atom with a particular proton/neutron combination.
An atom of a particular element distinguished by the number of protons and neutrons in its nucleus.
Nuclear species characterised by the number of protons (atomic number) and the number of neutrons. The total number of protons and neutrons is called the mass number of the nuclide.
elemental matter made up of atoms with identical nuclei, therefore with the same atomic number and the same mass number (equal to the sum of the number of protons and neutrons).
A species of atom characterised by the number of protons and neutrons and, in some cases, by the energy state of the nucleus.
An atom characterized by the number of protons, neturons, and energy in the nucleus.
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.
A nuclide (from lat.: nucleus) is a nuclear species which is characterized by the number of protons and neutrons that every atomic nucleus of this species contains.
