7.11 understand the term ‘half-life’ and understand that it is different for different radioactive isotopes

“Half-Life” is the amount of time taken for the activity of any radioactive substance to reduce to half. Each radioactive isotope decays in different speeds. So half life is different for different types of isotopes.
