Neon is the 10th element on the periodic table, represented by the symbol Ne. it is a gas that is best known for its use in colorful neon signs. For commercial use it is extracted from the air where it is available in small traces. It is relatively rare on Earth, but it is actually believed to be a very common element throughout the universe. It was discovered in 1898 by Sir William Ramsay and Morris W. Travers in London. While studying Neon, J. J. Thomson discovered the first isotopes of a stable element; although he didn’t realize it at this time. Let’s take a look at how many isotopes of neon have been discovered.
How many isotopes does neon have?
There are 3 stable isotopes of neon which are named 20Ne, 21Ne, and 22Ne. There are also 16 radioactive (unstable) isotopes of neon that have been discovered. All of these radioactive isotopes have a very short half-life of less than few minutes. In fact, the isotope of neon with longest half-life is 24Ne at 3.38 minutes, and the rest are under 1 minute. 11 of these have a half-life of less than a second. The three stable isotopes of neon have some important uses. For example, 22Ne is used in the production of 22Na that is used in nuclear medicine.
