Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered in 1898 by the British chemists Sir William Ramsay and Morris W. Travers.
Neon is chemically inert and forms no uncharged molecules. The most common compound of neon found on Earth is sodium chloride (common table salt). A relatively rarer example is the extremely volatile liquid organic compound known as dinitrogen tetroxide, which can be used as a rocket fuel.
Neon’s abundance in the universe has been estimated to be about one part per 750 million by volume. It is the second-lightest element in the periodic table after helium. Neon has few industrial applications, but its cultivation as an ornamental gas has led to widespread use in advertising and lighting, especially in Times Square in New York City and Las Vegas Boulevard in Nevada.
Neon is found in trace amounts in the Earth’s atmosphere. It is also found in some minerals, such as clevelandite. Neon is commercially extracted from air using liquefaction and fractional distillation.
Neon is the tenth element in the periodic table and is located in group 18. The elements in group 18 are called the noble gases. Neon is a gas at room temperature and is colorless, odorless, and tasteless. Neon is used in some lights and lasers.
Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered in 1898 by the British chemist Sir William Ramsay and Lord Rayleigh in London.
The name “neon” is derived from the Greek word ???? (neón), meaning “new”. Neon was the second of three inert gases to be discovered, and was immediately recognized as a new element from its bright red emission spectrum. The reason for neon’s extreme rarity on Earth (one part per million in the atmosphere) is that it is lighter than air and thus escaped from Earth’s gravity when it was formed during the Big Bang. Neon is abundant in the universe but rare on Earth.
Most neon found commercially is produced by electrical discharge in helium-neon plasma tubes. A small amount of neon is produced by extraction from liquid air. Commercial production started in 1923.
Neon is a gas that is used in signs and lamps. It is an inert gas that does not react with other elements. Neon is found in the air and is one of the noble gases. Neon was discovered in 1898 by Sir William Ramsay and Morris W. Travers.
