PhysicsRadioactivityGCSEAQA Created by: unicorns1234Created on: 02-11-18 10:38 If the nucleus has too few neutrons, it will emit a ‘package’ of two protons and two neutrons called an alpha particle 1 of 7 If the nucleus has too many neutrons, a neutron will turn into a proton and emit a fast-moving electron. This electron is called a beta particle 2 of 7 is an electromagnetic wave . It is at the small wavelength end of the electromagnetic spectrum gamma particle 3 of 7 the thing that radioactivity is detected with geiger muller 4 of 7 Radioactive decay is a process random 5 of 7 Half-life is the time it takes for half of the nuclei in a sample to decay unstable 6 of 7 is the time it takes for half of the unstable nuclei in a sample to decay half life 7 of 7
