How do scientists use the knowledge of radioactive dating

As the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate.Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4.6 billion years.How do scientists know the bones are really 68 million years old?Today's knowledge of fossil ages comes primarily from radiometric dating, also known as radioactive dating.

The ratio of parents to daughters can tell the researcher how old the specimen is.Atoms may have an equal number of protons and neutrons.If, however, there are too many or too few neutrons, the atom is unstable, and it sheds particles until its nucleus reaches a stable state.The same is true if you take a block away from one of the pyramid's sides, making the rest unstable.Eventually, some of the blocks can fall away, leaving a smaller, more stable structure.

The result is like a radioactive clock that ticks away as unstable isotopes decay into stable ones.
