As they decay the atoms change to daughter atoms, until eventually there won't be any of the original atoms left.
During a primary or secondary BEd, PGCE or GTP we hope that those learning to become science teachers will be able to challenge their own understanding of science and scientific concepts.
Unit K0 specifically explores general issues relating to all the knowledge units - to the learning of science.
We cannot predict exactly which atom will decay at a certain time but we can estimate, using the half-life, how many will decay over a period of time.
The half-life of a substance can be found by measuring the count-rate of the substance with a Geiger-Muller tube over a period of time.By plotting a graph of count-rate against time the half-life can be seen on the graph.
