This week, we meet the element that made the red light district what it is today, well sort of; what you're sure to see is a blaze of neon signs and with the story of how they came to be, here's Victoria Gill.
This could be the most captivating element of the periodic table. It's the gas that can give you your name or any word you like, in fact, in light.
Neon gas filled the first illuminated science, which were produced almost a Century ago and since then, it has infiltrated language and culture.
The word conjures up images of colourful or sometimes rather seedy, glowing science, many of which now don't contain the gas itself.
Only the red glow is pure neon, almost every other colour is now produced using argon, mercury and phosphorus in varying proportions, which gives more than a possible colours.
Nevertheless, it's neon that's now a generic name for all the glowing tubes that allow advertisers and even many artists to draw and write with light and it was that glow that gave its presence away for the first time.
Before it was isolated, the space it left in the periodic table was the source of years of frustration. With his discovery of Argon in and the isolation of helium that followed in , the British chemist, Sir William Ramsay had found the first and the third members of the group of inert gases.
To fill the gap, he needed to find the second. Finally, in at University College, London, Ramsay and his colleague, Morris Travers modified an experiment they tried previously, they allowed solid argon surrounded by liquid air to evaporate slowly under reduced pressure and collected the gas that came off first.
When they put the sample of their newly discovered gas into an atomic spectrometer, heating it up, they were startled by its glowing brilliance.
Travers wrote of this discovery, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget.
It was actually Ramsey's thirteen year old son, who suggested the name for the gas, saying he would like to call it novum from the Latin word for new.
His father liked the idea, but preferred to use the Greek. So a new element in name and nature, finally took its place in the periodic table.
And initially its lack of reactivity meant there were no obvious uses for Neon. It took a bit of imagination from the French engineer, chemist and inventor, Georges Claude, who early in the 20 th Century first applied an electric discharge to a sealed tube of neon gas.
The red glow it produced, gave Claude the idea of manufacturing a source of light in an entirely new way. He made glass tubes of Neon, which could be used just like light bulbs.
Claude displayed the first neon lamp to the public on December 11 th , at an exhibition in Paris. His striking display turned heads but unfortunately sold no neon tubes.
People simply didn't want to illuminate their homes with red light; but Claude wasn't deterred. He patented his invention in and during his quest to find a use for it he discovered that by bending the tubes, he could make letters that glowed.
The use of neon tubes for advertising signs began in , when his company Claude Neon, introduced the gas filled tubular signs to the United States.
He sold two to a Packard car dealership in Los Angeles. The first neon signs were dubbed 'liquid fire' and people would stop in the street to stare at them, even in daylight, they glow visibly.
These days neon is extracted from liquid air by fractional distillation and just a few tons a year of the abundantly available gas is enough to satisfy any commercial needs.
And of course there are now many sources of illuminated signs, screens and displays that give us far more impressive scrolling letters and moving pictures that we associate with the bright colourful lights of say Times Square in New York City.
So Neon might have lost some of its unique lustre here on Earth, but further away, it has helped reveal some secretes of the most important glowing object for our planet, the Sun.
Solar particles or solar wind also contain Neon in the ratio of two neon isotopes in Moon rock samples, rocks that get blasted by the solar wind for billions of years had until recently baffled scientists.
This is because the ratio of the two isotopes varied according to the depths in the rock; with more neon than neon at lower depths. So did this mean that the sun had once been significantly more active than it is today, shooting out higher energy particles that could penetrate deeper into the rocks?
This question was finally answered when scientists studied a piece of metallic glass that had been exposed to the solar wind for just two years on the Genesis spacecraft, which crashed to Earth in When scientists measured the distribution of Neon in the glass samples, exposed to solar wind, they found the top layer also contained more neon than the underlying layer.
The underlying layer was similar to the moon rock. Since the activity of the sun was very unlikely to have changed during the two-year mission, it seems that a type of space erosion was causing the discrepancy, micrometeoroids or the particles simply removed some of the original neon from the top surface of the lunar rock.
So may be you should stop and dwell upon the next neon sign you see and just appreciate a truly unique glow. So, an element that's as at home in outer space, as it is advertising a brand name here on Earth.
That was Victoria Gill with the story of neon. Next time, to the chemical that ironed out the wrinkles in steel making. When Sir Henry Bessemer invented the process of steel making in , his steel broke up when hot rolled or forged; the problem was solved later that year, when Robert Foster Mushet, another Englishman, discovered that adding small amounts of manganese to the molten iron solves the problem.
Since manganese has a greater affinity for sulfur than does iron, it converts the low-melting iron sulfide in steel to high-melting manganese sulfide.
But how did it work, Ron Caspi will be here next week with the story of manganese, the element that makes photosynthesis feasible and gave us an alternative to green glass.
That's on next week's Chemistry in its element; I hope you can join us. I'm Chris Smith, thank you for listening and goodbye!

Stable isotopes of neon are produced in stars. Neon's most abundant isotope 20 Ne This requires temperatures above megakelvins , which occur in the cores of stars of more than 8 solar masses.
Neon is abundant on a universal scale; it is the fifth most abundant chemical element in the universe by mass, after hydrogen, helium, oxygen, and carbon see chemical element.
Neon is monatomic, making it lighter than the molecules of diatomic nitrogen and oxygen which form the bulk of Earth's atmosphere; a balloon filled with neon will rise in air, albeit more slowly than a helium balloon.
Neon's abundance in the universe is about 1 part in ; in the Sun and presumably in the proto-solar system nebula, about 1 part in The Galileo spacecraft atmospheric entry probe found that even in the upper atmosphere of Jupiter, the abundance of neon is reduced depleted by about a factor of 10, to a level of 1 part in 6, by mass.
This may indicate that even the ice- planetesimals which brought neon into Jupiter from the outer solar system, formed in a region which was too warm to retain the neon atmospheric component abundances of heavier inert gases on Jupiter are several times that found in the Sun.
Neon comprises 1 part in 55, in the Earth's atmosphere , or It comprises a smaller fraction in the crust. It is industrially produced by cryogenic fractional distillation of liquefied air.
Neon is the first p-block noble gas, and the first element with a true octet of electrons. It is inert : as is the case with its lighter analogue, helium , no strongly bound neutral molecules containing neon have been identified.
They can be extracted by placing the clathrate into a vacuum chamber for several days, yielding ice XVI , the least dense crystalline form of water.
The familiar Pauling electronegativity scale relies upon chemical bond energies, but such values have obviously not been measured for inert helium and neon.
The Allen electronegativity scale , which relies only upon measurable atomic energies, identifies neon as the most electronegative element, closely followed by fluorine and helium.
Neon is often used in signs and produces an unmistakable bright reddish-orange light. Although tube lights with other colors are often called "neon", they use different noble gases or varied colors of fluorescent lighting.
Neon is used in vacuum tubes , high-voltage indicators, lightning arresters , wavemeter tubes, television tubes, and helium—neon lasers.
Liquefied neon is commercially used as a cryogenic refrigerant in applications not requiring the lower temperature range attainable with more extreme liquid-helium refrigeration.
Driving neon's expense is the rarity of neon, which, unlike helium, can only be obtained from air. The triple point temperature of neon From Wikipedia, the free encyclopedia.
