· Sources of Neon: It can be prepared by liquification of air and separated from other elements by fractional distillation. Annual world production is around 1 ton. · Uses of Neon: In a vacuum tube, neon glows reddish orange, thus, the invention of the neon lights.
Neon is a chemical element with 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 (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed.
We are discussing the atomic structure of Carbon, Nitrogen, Oxygen, Fluorine and Neon. We shall see that the electrons being added to the l shell which is the outer most shell for these elements and the l shell reaches its maximum capacity in Neon.
The atomic structure of an atom is generally an amount of electrons orbiting a nucleus of protons and neutrons. The nucleus comprises most of the atom and the electrons are infinitesimally small.
While it is inert, there have been reports of it combining with fluorine. Neon may also form ions in combination with other noble gases (NeAr, HeNe, Ne 2 and with hydrogen (NeH). It also forms an unstable hydrate, so it is not nearly as inert as one might think. Neon Menu. Neon Page One. Overview of Neon; Neon's Name in Other Languages; Atomic ...
There are no common compounds using neon. Interesting facts: It is the fourth most abundant element in the universe, but only it represents only 0.0018% of the earth's atmosphere. It is the second lightest noble gas. The neon sign was first used by Georges Claude in Paris in 19l0. Common Uses: Neon lights; Gas lasers; Lightening arrestors
/Experimental Therapy/ Neon ion radiotherapy possesses biologic and physical advantages over megavoltage X rays. Biologically, the neon beam reduces the oxygen enhancement ratio and increases relative biological effectiveness. Cells irradiated by neon ions show less variation in cell-cycle related radiosensitivity and decreased repair of radiation injury.
The use of neon tubes for advertising signs began in 1923, 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.
