Neon is a rare gas that occurs in the Earth’s atmosphere and is used in lighting. It is a member of the noble gases, which are the most stable and least reactive elements with full valence shells. It is odorless and colorless and monatomic (exists as individual atoms).
The chemical element neon was discovered in 1898 by Sir William Ramsay, a Scottish chemist, and Morris Travers, an English chemist. They were looking for krypton, argon and xenon when they ran across the new element.
When a current runs through the gas, it gives off a reddish orange light called neon. It is used in many different types of signs that glow, like those in restaurants and shops.
A lot of people get a thrill from seeing the bright, reddish-orange lights that are created when a neon tube is filled with the gas. They are usually a glass tube with electrodes on both ends.
Some of the other colors that can be created with these gases are green and blue. There are many different colored indicators that use these gases, including those used in high voltage instruments and lasers.
Using the Periodic Table to learn more about Neon
The periodic table is a chart that arranges all the chemical elements based on their atomic number and other properties. This makes it easy to find out more about any chemical element.
