Aqa Gcse Physics 4 4 2 3 Atomic Structure Half Lives The Random Atomic structure. positively charged nucleus (which contains neutrons and protons) surrounded by negatively charged electrons. subatomic particle relative mass relative charge proton 1 1 neutron 1 0 electron 0 (0.0005) 1. typical radius of an atom: metres. and the radius of the nucleus is 10 000 times smaller. Key fact. half life is the time it takes for half of the unstable nuclei in a sample to decay or for the activity of the sample to halve or for the count rate to halve. count rate is the number of.
