Q: Who discovered neon?A: Two British chemists: Sir William Ramsay and Morris W. Travers of London, England.--------------------------------Q: When was neon found?A: Neon was found in 1898.

Neon, as mentioned before, gives off a bright red-orange light naturally. It is combned with fluorescent lighting and other elements to produce a variety of other colours. (eg. when mercury is added, it gives off a bright blue hue). These lighting effects can be used for interior designing.Neon's unmistable shine is a natural attention-grabber. Neon is mostly used today for signs and advertisements. When combined with helium gas, lasers can be created. Next time you're playing laser tag, you'll know who to thank!Other uses:~High voltage indictatos.~Lighting arrestors.~TV tubes.

How is it used?

Atomic mass: 20.1797Atomic number: 10# of protons: 10# of neutrons: 10# of electrons: 10.1797Combining capacity: 0Group/Famlily: #18 / Noble GasesPhysical properties:~Melting point: -248.59 degrees Celsius~Boiling point: -246.08 degrees Celsius~Density: 0.9 x 10(-3) g/cm3~Neon is colourless, odourless nad tasteless. When it is electrically discharged though, it naturally gives off a reddish-orange glow.Chemical properties: ~Neon is chemically inactive! It does not easily combine with other elements because its valence shell is full! (8) Thus, neon is already chemically stable, which means it doesn't give or take electrons.~There are currently no known compounds formed by neon and other elements. But scientists are hard at work looking for them. Several experiments have been conducted which showed a possibility of a neon and fluorine compund, though. [(Ne+, (NeAr)+, (NeH)+, (HeNe)+]. Unfortunately, this study has not been verified....BUT...In glass tubes used for fancy lighting, neon is mixed with small portions of other elements to produce other colours. (Most commonly argon, phosphor, xenon, helium and mercury). The elements are reacting with the inside coating of the glass tubes, rather than with each other.

Before the 1890s, scientists had already discovered several elements present in the air. Oxygen and nitrogen were the first two to be found (in 1770), followed by argon. Altogether, the elements fill up about 99.966% of the air. Scientists were still very determined to find out what the other miniscule fraction was composed of.Since equipment wasn't advanced enough during the 1890s, scientists couldn't rely on it to take small samples of air. Instead, they turned to spectroscopy: a different method to help differentiate the many components of our atmosphere.Ramsay and Travers used this method to discover neon, one of the 5 elements found between 1895 and 1990. First, they cooled a sample of air until it condensed. Then, the liquid obtained was warmed and they would capture the gas released while it boils. Light patterns are emitted when elements are heated, which can be used for studying their properties. Ramsay and Travers caught a glimpse of a reddish spectrum that glowed dramatically. Never before had they seen anything quite like it, thus they were astonished by what was before their very own eyes.Finally, another fraction of our atmosphere was found! Soon after, the element was given the name 'neon', which means 'new'.Afterall, this was one of the most exciting and newest discovery in the late 19th century!

History

Where is Ne located on the periodic table?

In our atmosphere. Along with many other elements such as oxygen, nitrogen, argon... etc., neon occupies about 0.0182% of the air around us! It is the 5th most abundent element in the UNIVERSE, but it is rare on EARTH. How do we get it? Well, we use fractional distillation to liquefy the air to obtain neon in its liquid state.
