So geologists have assumed these radioactive decay rates have been constant for billions of years. Because of such contamination, the less-thanyear-old lava flows at Mt. Atoms—Basics We Observe Today Each chemical element, such as carbon and oxygen, consists of atoms unique to it. When a geologist today collects a rock sample to be dated, he has it analyzed for the parent and daughter isotopes it contains—for example, potassium and argon However, while the number of neutrons varies, every atom of any chemical element always has the same number of protons and electrons. The scientists who interpret these amounts of A and B to conclude that millions of years have passed must first assume three main things about the rock: At time zero, the hourglass is turned upside-down so that all the sand starts in the top bowl. However, this is an enormous extrapolation of seven orders of magnitude back through immense spans of unobserved time without any concrete proof that such an extrapolation is credible. If B was in the rock before it hardened.
