7- Atomic and Nuclear Flashcards
When a Nucleus emits a beta particle…
It loses 1 neutron and gains 1 proton
α (name, mass, charge)
Alpha, 4, 0
β- (name, mass, charge)
Beta/electron, 0, -1
γ (name, mass, charge)
Photon, 0, 0
v with line, (name, mass, charge)
Antineutrino, 0, 0
Radioactivity is caused by a nuclide having too many…
Neutron or protons
Term for atom characterised by nucleus (number or protons and neutrons)
Nuclide
Beta + decay is when a neutron breaks down into…
proton, beta particle, antineutrino
Binding energy
The amount of energy released when a nucleus is assembled from its component nucleons, or the amount of energy needed to separate a nucleus into its individual nucleons.
Nucleon
Proton or neutron
Electronvolt
Energy gained/lost by one electron as it moves through a potential difference of 1 volt
Gamma radiation
Photons of high energy radiation emitted as a result of a nucleus changing from an excited state into a lower energy state
Isotope
Nuclides that contain the same number of protons, so are the same element, but different numbers of neutrons
Nucleon
Collective name for neutrons and protons
N number
Number of neutrons in a given nuclide
