Neon was named from the Greek word for new, neos, by its discoverer Sir William Ramsey.Sir William's main passions in life were far eastern and Greek culture and archeology but his fame came from his work in Chemistry. In 1898 Ramsey and his colleague Morris Travers were studying liquid air and trying to identify all the components. Scientists had already discovered that air was made up of 99.96 percent Oxygen, Nitrogen and Argon but now they wanted to know what the remaining 0.04 was.
Ramsey had already identified Argon and Helium. He theorized that these were the first and third members of the group of gases and so knew roughly what he was looking for, but how do you identify something that's main defining characteristic is that it is inert? He is quoted: "Here is a supposed gas, endowed no doubt with inert properties, and the whole world to find it in."
On 30 May 1898 they isolated a new gas, but it was Krypton, not the one they were looking for. In June they took some of their isolated Argon and froze it by enclosing it in a glass bubble and surrounding this with liquefied air. They extracted the liquid produced and passed electricity through the vapor that was left. This colored lines, the spectra. These lines were a bright yellow, a faint violet and a faint green and a red color. Further extraction led to a red bulb. The flare of red light produced must have been very dramatic, as Ramsey said," The blaze of crimson light from the tube told its own story, and it was a sight to dwell upon and never to forget."
Ramsey's son wanted to call the new gas novum, and this combined with the idea of keeping the family names similar led to the naming of the gas as Neon. On 12 July 1898 Ramsey and his student identified Xenon.
They had identified three members of the inert gas family in six weeks. Ramsey went on to identify Radon in 1900. His work on the inert gases was rewarded with a Noble prize in 1904.
Ramsey's discoveries turned him into something of a celebrity in London society and he was so well known that he even became the subject of Cartoons in the press.
Neon's main use is in Neon lights but its inertness has led to its use in other fields. It can be used in cryogenics at it reacts with nothing else at all. Neon is a better and less expensive refrigerant than helium. It has no known biological function. Its used in many scientific instruments and tools for detecting electrical current, as well as in television tubes.
It was a French scientist, George Claude that made the first neon bulbs in 1902. Having had little success selling bulbs that glowed bright red to householders in Paris he worked on signs made with bent tubes of glass acting as light bulbs. These were introduced to Paris in 1912 and became popular advertising tools. These were first brought to America by the Packard motor company of California in 1923, but soon became one of the defining symbols of the American dream. By adding Argon, Mercury, and Phosphorous to the tubes in varying proportions there are now over one hundred and fifty colors available.
Neon was discovered by the Scottish Chemist named Sir William Ramsay and fellow English chemist Morris M. Travers shortly after they discovered the element krypton in 1898.
Krypton was discovered during an 1898 study of liquefied air. It was discovered by chemist Sir William Ramsay, along with chemist Morris M. Travers on May 30.
Found in earths atmosphere (0.0001% of earths atmosphere). Discovered by Sir William Ramsay, a scottish chemist, and his student Morris M. Travers, Englishman.
Krypton was discoverd by Scottish chemist Sir William Ramsay in 1898 when studying the properties of liquified air. After the liquid air boiled away liquid krypton was left behind.

Examples are helium, neon, argon.
Some dinoflagellates give off light. A chemical reaction in the cells produces light similar light produced by a firefly. water filled with these dinoflagellates glows like a twinkling neon light.
We can generally say that there are 10 electrons in all neon atoms, regardless of which isotope we consider. Neon is a noble or inert gas. It doesn't want to react with any other atoms. That means it wants to hang onto all its electrons, neither wanting to loan or borrow any. Regardless of the number of neutrons in the nucleus of a neon atom, it's still neon, and will have 10 electrons under normal circumstances.
Xenon was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers on July 12, 1898, shortly after their discovery of the elements krypton and neon. They found xenon in the residue left over from evaporating components of liquid air.
After bombarding with alpha particles some elements (e.g. Be) it was observed that a strange radiation is emitted; Chadwick in 1932 showed that this radiation has neutral particles with a mass similar to the mass of proton. The proposed name was neutrons.

Gas in most normal circumstances.
There are no common reactions by neon. Although it can be forced into some reactions when under extreme conditions, neon is a noble gas with a complete octet of electrons, therefore it does not react under normal circumstances.
Water, under normal cirumstances, has a density of about 1 gran per cubic centimeter. Under normal circumstances, Neon has a density of a little over .9 grams a liter(1000 cubic centimeters). This means Neon is less dense. In this sense, if Neon were placed in water it would escape to the surface because it is a gas. However, it will not float on the surface.
neon was discovered by a Scottish chemist, William Ramsay, and a English chemist Morris travers, a little after their discovery of krypton. Neon and krypton were discovered through the study of liquified air. Neon was discovered when ramsay chilled a sample of The atmosphere until it was a liquid, then he warmed it, and captured the gasses as it boiled

Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of the element krypton in 1898. Like krypton, neon was discovered through the study of liquefied air. Although neon is the fourth most abundant element in the universe, only 0.0018% of the earth's atmosphere is neon.The largest use for neon gas is in advertising signs. Neon is also used to make high voltage indicators and is combined with helium to make helium-neon lasers. Liquid neon is used as a cryogenic refrigerant. Neon is highly inert and forms no known compounds, although there is some evidence that it could form a compound with fluorine.
That is because Neon is a noble gases and noble gases do not bond under normal circumstances. This is because they have a complete set of 8 valence electrons and it does not want to gain or lose any.
