Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.

Here’s an example using the simplest atom, hydrogen. Carbon-14 is an unstable isotope of carbon that will eventually decay at a known rate to become carbon-12.

Despite the fact the designers opted for a square-like shape to the tubes, the lines of the Gallium’s frame are really catchy.

The Canadian manufacturer used two different designs for the bottom and the top of the frame: the lower one responsible of the rigidity of the bike, and the top one focused on the comfort for the rider (HDS; Horizontal Dual System).

It might have been because of its geometry, but when I firstly hopped on the Argon 18 Gallium Pro, I felt the Canadian bike fitted me perfectly.The most widely known form of radiometric dating is carbon-14 dating.This is what archaeologists use to determine the age of human-made artifacts. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.And if the artifact is organic—like wood or bone—researchers can turn to a method called radiocarbon dating.
