The loss of those neutrons is called radioactive decay. For carbon, the decay happens in a few thousand years (5,730 years).

Some elements take longer, and others have a decay that happens over a period of minutes.

Archeologists are able to use their knowledge of radioactive decay when they need to know the date of an object they dug up.

C-14 locked in an object from several thousand years ago will decay at a certain rate.

Since you never really know which carbon atom you are using in calculations, you should use the average mass of an atom.

For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).

With their knowledge of chemistry, archeologists can measure how many thousands of years old an object is.

Although more studies are needed on cannabis (marijuana) secondhand and thirdhand smoke, some data already available shows …

They only escaped being poisoned by the hazardous gas because they were staying on the floor below the leak.

But still, the number of youngsters treated in hospital for suspected gas poisoning rose to 16 yesterday afternoon.
