) is only 5,730 years—that is, every 5,730 years, half of it decays away.
What methods do they use and how do these methods work?
In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
You probably have seen or read news stories about fascinating ancient artifacts.
At an archaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.
Radiocarbon dating or in general radioisotopic dating method is used for estimating the age of old archaeological samples. In the upper atmosphere, nitrogen (C in a living plant, were can estimate the age of the object (the age of the object means the number of years ago when plant should have died), by using the formula.
For example, age of the earth, moon, rocks, and mineral deposits can be determined by using the principle of radioisotopic dating. Age of the carbon containing object = t C in it, is called radiocarbon dating. Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.All carbon atoms have a nucleus containing six protons.Here you can publish your research papers, essays, letters, stories, poetries, biographies, notes, reviews, advises and allied information with a single vision to liberate knowledge.

While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years.
