Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. 1. An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.

What is the definition of radiocarbon dating in chemistry?

Carbon-14 dating, also called radiocarbon dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14). Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

What is the use of radiocarbon dating?

Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. It can be used on objects as old as about 62,000 years.

Can aluminum be broken down by chemical means?

A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound.
