The Age of the Solar System Radioactive elements decay into stable ones; e.g., The rate of decay is fixed by the element’s half-life, the time for 50% to decay; for 40K, this time is 1.25 Gyr (1 Gyr = 1 billion years). Rocks contain no 40Ar when they form; by measuring the ratio of 40Ar to 40K, the rock’s age can be found. (Potassium-40) (electron) (Argon-40) ...read more
