Gcse physics radioactive dating

gcse physics radioactive dating Radioactive decay is a random process you cannot predict when an individual nucleus will decay but with large numbers of nuclei you can use a statistical approach activity the activity of a sample is the average number of disintegrations per second its unit is the becquerel (bq) one becquerel is one decay per second.

The half-life: the length of time taken for half of the atoms in the sample to decay constant for a particular event ie elementshave known half-lives half-lives vary between different radioactive elements from seconds to billions of years a sample of isotope's activity can be plotted against time on a graph to. Most of them are radionuclides, meaning they are unstable and undergo radioactive decay there are nearly 4000 known isotopes and 580 nuclear isomers. Comprehensive revision notes for gcse exams for physics, chemistry, biology. Uk secondary school physics, free downloadable teaching resource this radioactive decay is completely spontaneous for now, for gcse exams, let's go along with the idea that the rate of radioactive decay does not depend on external.

Modelling radioactive decay when a radioactive nucleus decays, it does so randomly you can't predict when it will happen lots of nuclei of the same isotope, however, will decay following a pattern called a radioactive decay curve the decay of radioactivity in a radioactive element can be modelled using cubes, dice or.
