The amount of 40 Ar formed is proportional to the decay rate half-life of 40 K, which is 1. The principles of original horizontality, superposition, and cross-cutting relationships allow events to be ordered at a single location. Negatively charged subatomic particles with very little mass; found outside the atomic nucleus electron spin resonance:
