Gold has 41 Isotopes But Only One Is Stable

Most people would be thrilled to find some gold in the nature because it is a fairly well-known element. In contrast to many other metals, it doesn't corrode and is quite valuable. There are actually 41 known isotopes of the metal, which is something that is less generally recognized. The only stable isotope of gold that humans are aware of and desire is gold-197. The remaining forty are all radioactive.

Interesting stability is observed with gold-197. This indicates that although science predicts it should be radioactive, observation contradicts this prediction. So, unlike what you may assume, it just isn't radioactive. That has generally benefited practically every economy throughout history.

By using half-lives, we can gauge radioactivity in one way or another. The length of time it takes for half of a sample of a radioactive isotope to experience a nuclear decay event is known as the radioactive half-life. If a radioactive substance has a sample with a half-life of one day, just half of your sample will still contain the original substance after that time. The remaining portion could transform into several isotopes of the same element or atoms of a different element.
