What is half-life?
The time taken for half the mass of a radioactive isotope to decay
The time taken for all of a radioactive isotope to decay
Half the time taken for a nuclear bomb to explode
A computer game
How is the half-life of a radioisotope similar to a sports tournament where the losing team is sent home?
They both have exponential decay to the power of 2
They both drop by one every time something happens
They both end up with half what they started with
Every half life, approximately half the atoms decay into a more stable isotope.
