How much of a radioactive parent isotope remains after one half-life has passed?
all of the parent isotope because half-life refers to the time it takes for half of a radioactive substance to undergo radioactive decay
half of the original amount because half-life refers to the time it takes for half of a radioactive substance to undergo radioactive decay
one quarter of the original amount because half-life refers to the time it takes for half of a radioactive substance to undergo radioactive decay
