In the example below, the bone must date to sometime between 1.75 and 1.5 million years ago.
One half-life is the amount of time required for of the original atoms in a sample to decay.
As a result, there is a changing ratio of carbon-14 to the more atomically stable carbon-12 involves actually counting individual carbon-14 atoms.
This allows the dating of much older and smaller samples but at a far higher cost.
The atoms of crystalline solids, such as pottery and rock, can be altered by this radiation.
Specifically, the electrons of quartz, feldspar, diamond, or calcite crystals can become displaced from their normal positions in atoms and trapped in imperfections in the crystal lattice of the clay molecules.
