A diagram with 3 yellow squares with arrows pointing to indicate steps. The first yellow square has all white dots and is labelled "Time 1: pure parent isotope," the second/middle yellow square has half white dots and half green dots (labelled as the daughter isotopes) and is labelled "After 1 half life: 1/2 parent and 1/2 daughter isotope," and the third yellow square has a quarter white dots and three-quarters green dots and is labelled "After 2 half lives: 1/4 parent and 3/4 daughter isotopes."
