Radioactivity 0.0 / 5 ? PhysicsRadioactivityGCSEOCR Created by: Kieren James SaddlerCreated on: 12-04-15 12:52 What is the number of neutrons in an element? Not fixed 1 of 11 What does every atom of a particular element have? The same number of protons in its nucleus. The number of neutrons is not. 2 of 11 What do many elements have a few different types of? Isotopes 3 of 11 What are isotopes? Atoms with the same number of protons but different numbers of neutrons 4 of 11 What happens if the nucleus is unstable? It decays and emits radiation 5 of 11 What radiation do radioactive elements emit? Ionising radiation 6 of 11 What do unstable atoms do? Decay at random (it is unpredictable). 7 of 11 What is the decay of unstable atoms not effected by? Physical conditions or chemical processes 8 of 11 What are the three types of ionising radiation? Alpha, Beta and Gamma 9 of 11 What can ionising radiation cause? The atom to change into a new element 10 of 11 What can ionising radiation cause to happen apart from changing the atom into a new element? It can transfer enough energy to break an atom/molecule into ions. These new ions can go onto to partake in other chemical reactions. 11 of 11
