The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.
This atom is not stable, and will break down, releasing nuclear energy in the process.
Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.
Cosmic rays are positively charged atoms moving at enormous speeds.
Uranium 235 decay to lead has a half-life of 713 million years, so it is well suited to dating the universe.
Radiometric dating is the method for establishing the age of objects by measuring the levels of radioisotopes in the sample. It decays to nitrogen 14 with a half life of 5730 years.
When their dating methods say that something lived 30,000 years ago, they sound certain.
And on the basis of these methods, many scientists announce that the Bible's record of history is not accurate.
