Largest number of stable isotopes in one element

Every element in the Periodic Table has variations of itself called an Isotope. Isoptopes only differ from the basic element by the number of neutrons contained within the nucleus of the atom. Isotopes can be stable or unstable, and they decay by emitting radiation. The element with the largest number of stable isotopes is tin (symbol Sn and atomic number 50) with 10 isotopes. Tin was first extracted and used in the Bronze Age (circa 3000 BC). Together with copper, it formed the alloy bronze. It is the 49th most abundant element on Earth, where it is found in common ores such as cassiterite (tin dioxide). China and Indonesia have the largest current reserves of tin, followed by Brazil, Bolivia and Russia.
