DOC Half-Life Radioactive Isotopes The half-life is a measure of how much time it takes for ½ of a sample of radioactive atoms to decay into stable, or non-radioactive, atoms. After one half-life passes, only ½ of the atoms are still radioactive - the other half are stable. After a second half-life passes, another ½ of the remaining radioactive atoms have decayed into stable nuclei. radioactive elements worksheet 40 Half Life Worksheet Chemistry - combining like terms worksheet. 11 Pictures about 40 Half Life Worksheet Chemistry - combining like terms worksheet : A List of Radioactive Elements, A List of Radioactive Elements and also Radioactivity alpha/beta/gamma sheet (GCSE) by sparrigan - Teaching.
