    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.

    It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. 1979, 1986 © Harper Collins Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012 Cite This Source radiocarbon dating A technique for measuring the age of organic remains based on the rate of decay of carbon 14.Because the ratio of carbon 12 to carbon 14 present in all living organisms is the same, and because the decay rate of carbon 14 is constant, the length of time that has passed since an organism has died can be calculated by comparing the ratio of carbon 12 to carbon 14 in its remains to the known ratio in living organisms. Our Living Language : In the late 1940s, American chemist Willard Libby developed a method for determining when the death of an organism had occurred.Libby thus reasoned that by measuring carbon 14 levels in the remains of an organism that died long ago, one could estimate the time of its death.This procedure of radiocarbon dating has been widely adopted and is considered accurate enough for practical use to study remains up to 50,000 years old.

      So, lets look at a few typical examples of bad profiles: “I am not good at writing about myself, but my friends say that I am intelligent, professional, educated and ambitious. I am looking to a meet an intelligent, beautiful woman for dating and relationship.” – at first, this looks like a well-written profile by a guy who seems to have head on his shoulders. There is nothing “catchy” about this profile – there is nothing that would compel a reader to stop and respond to it.

      Sağ ayağı çatlamış, önemli birşeyi yoktu, ama üzerine çok zor basıyordu. Çağrı da gördükleri karşısında kendini zor toparladı ve “Yaa çok özür dilerim, pardon, çok pardon! Bense utancımdan annemler gelene kadar odamdan çıkamadım. Ben de bu düşünceler arasında uyumaya çalışırken, sessizce odamın kapısının açıldığını farkettim.
