More information
Neon was discovered in 1898 by Sir William Ramsay and Moris William Travers. The name comes from the Greek "νέον" (neon) meaning "new one". Neon, krypton and xenon are known as "rare" gases, since combined they only account for one thousandth of the air which surrounds us. These gases are colorless and tasteless. They are so inert that they do not react and can only be combined with other chemical substances with great difficulty. Their extreme inertness makes them very valuable for certain applications.
