Cards in this deck (8)

1What are isotopes?Versions of the same element with a different number of neutrons but the same number of protons
2What is a nucleon?A proton or neutron
3What is a nuclide?A specific kind of atom or nucleus characterized by its number of protons and neutrons
4What is specific charge?The charge of a charged particle, divided by its mass
5What is the strong nuclear force?The strong nuclear force is the force of nature which opposes & overcomes the electrostatic repulsion of protons in a nucleus, holding nuclei together.
6List properties of the strong nuclear force (range, which particles it effects, attractive force variance)It has a range of 3-4 femtometres (1*10^15m)
It has the same effect between two protons as it does between two neutrons or a proton and a neutron
It is an attractive force from 3-4 fm down to 0.5 fm. Closer than this, it is a repulsive force that actits to precvent neutrons and protons being pushed into each other
7List the 3 types of radioactive decay and what they are made ofAlpha radiation: alpha particles which are helium nuclei (2 Protons 2 neutrons)
Beta radiation: beta particles which are fast-moving electrons (emitting a beta particle increases charge by 1 because they are negatively charged)
Gamma radiation: electromagnetic radiation which has no mass or charge
