Once a living thing dies, it nolonger takes in carbon from food or air, and the amount of carbon-14 starts to dropwith time. For example carbon has isotopes of weight12, 13, and 14 times the mass of a nucleon, referred to as carbon-12,carbon-13, or carbon-14 (abbreviated as 12c, 13c, 14c). Lisa "left eye" lopes meets andre rison. This would most likely be the case in eitheryoung rocks that have not had time to produce much radiogenic argon, or in rocksthat are not abundant in potassium.
