With its discovery in 1896, radioactivity opened up a Pandora's box of questions and revealed a new world, waiting to be explored in the microcosm of the atomic nucleus. Radioactivity is a very interesting phenomenon in nature.By Chemicool's calculations, that translates to 65 trillion metric tons — and the number increases over time as potassium-40 decays.According to the Jefferson National Linear Accelerator Laboratory, the properties of argon are: The first hint of argon's existence came in 1785, when British scientist Henry Cavendish reported a seemingly inert portion of air, according to the RSC.On Earth, the vast majority of argon is the isotope argon-40, which arises from the radioactive decay of potassium-40, according to Chemicool.But in space, argon is made in stars, when a two hydrogen nuclei, or alpha-particles, fuse with silicon-32. (Isotopes of an element have varying numbers of neutrons in the nucleus.) Though inert, argon is far from rare; it makes up 0.94 percent of Earth's atmosphere, according to the Royal Society of Chemistry (RSC).
