Report On Neon Essay, Research Paper

Neon was discovered in 1898 by British chemists Sir William Ramsay and Morris W. Travers as a constituent of the most volatile fraction of liquified petroleum Ar obtained from air. Upon using an electric current to it, the chemists found that it had an orange freshness, and they decided that it was non argon, but instead a new component wholly.

Neon is non a really common component, but the topographic points it is most abundant in are the Earth & # 8217 ; s atmosphere, and trapped within stones in the Earth & # 8217 ; s crust. The topographic point where it is most abundant, nevertheless, is the throughout the universe. In the Earth & # 8217 ; s atmosphere, neon lone comprises 0.0018 per centum of the volume. On the Earth, Ne is ever present as a gas.

There are many physical belongingss of Ne, such as the fact that it is colourless, odourless, and tasteless. Besides, Ne is lighter than air. With a denseness of denseness 0.89990 g/liter. The freezing point of Ne is -248.67? C, and the boiling point of Ne is -246.048? C, which is even lower than the boiling point of N ( -195.8? C ) . When under low force per unit area, neon emits a bright orangish-red freshness if a little electric current is passed through it. The negatron constellation of Ne is 1s22s22p6. The chemical belongingss of Ne include the fact that it is non reactive because it has a full outer shell

, and hence can non derive or lose any negatrons. Because of this, neon belongs to a group of elements called β€œnoble gases.” These are all gases which have a full outer shell and can non respond in nature. The period of Ne is 2, and the group is 18.

Neon has an atomic figure of 10, and a mass of 20.180. Neon has three stable isotopes: Ne 20, 21, and 22. These three isotopes comprise 90.92 per centum of natural Ne, 0.26 per centum of natural Ne, and 8.82 per centum of natural Ne, severally. There are five other isotopes of Ne, and they are all radioactive. None of these five isotopes occur in nature.

There is merely one common usage for Ne, and that is in electric and fluorescent visible radiations to bring forth a bright orangish-red freshness.

Neon is produced industrially by distillment of liquified air. The most volatile portion of the liquid air is comprised of N, Ne, and He. The N is removed by condensation under increased force per unit area, and lowered temperature. Then, the N is adsorbed by extremely cooled wood coal. Neon is separated from He by selective surface assimilation on activated wood coal at low temperatures. Extracting Ne from air is drawn-out, and produces merely 1 lb of Ne for every 88,000 lbs of air that is processed.
