Which gaseous elements are inert

Group No. Period Number. Noble Gas Element. Atomic Number. Electronic Configuration. He was awarded the Nobel Prize of Chemistry in for his achievements.

There are numerous uses of inert gases or noble gases in various fields specially in the field of metallurgy. Here we are listing few applications of each inert gas separately in many fields —. Helium is used for the treatment of asthma, emphysema and other breathing problems. Helium is used in balloons. Helium is used in welding. Helium is used in industries for preventing explosions. Helium is used for cryogenics. Liquid Helium is used for magnetic resonance imaging.

Helium is used in semiconductor processing. Helium is used in laser processing as well. We used to use Neon in television tubes. Neon is also used in cryogenics. Neon is used in sign boards as on passing electricity it glows brightly. Neon is used in lasers. Neon is used in wave meter tubes. Neon is used to shield electrical equipment from lightning. Neon is used in lighting systems such as lamps etc.

When helium was found on Earth in the late 's in association with uranium ores , it was found to have the same emission spectrum as the element previously found in the Sun, indicating that it was indeed the same element. The concentration of helium in the Earth's crust is about 8 ppb, making it the 71st most abundant element; it is found in the atmosphere at a concentration of 5 ppm by volume.

It is found in some minerals, where it is produced by radioactive elements that decay by alpha particle emission see below. Of course, there's also "dark matter" and "dark energy" to worry about, but that's another story. Hydrogen, helium, and trace amounts of lithium were produced at the beginning of the Universe in the Big Bang, and became concentrated into stars by the force of gravity.

The fusion of hydrogen atoms in stars to produce helium produces huge amounts of energy; the energy in sunlight is captured by plants in photosynthesis, and drives most of the chemistry of living organisms. The most common isotope of helium, helium-4, consists of two protons and two neutrons in the nucleus, surrounded by two electrons.

Helium is found along with some radioactive minerals that decay by alpha particle emission, however the concentration of helium in these minerals is very low. The main source of helium is from natural gas, where it is separated out from the other components by fractional distillation.

Helium liquefies at 4. Some materials become superconductors when immersed in liquid helium; in these materials, there is no resistance to the flow of electricity. Superconducting magnets are used for an important medical imaging technology called Magnetic Resonance Imaging MRI , which allows images of tissues and organs to be obtained. A related technology is used by chemists to obtain information that can be used to deduce the structures of molecules; this technique is called Nuclear Magnetic Resonance NMR ; the two technologies are basically the same, but the term "nuclear" is avoided in the medical application because of its unpleasant associations even though there is no nuclear radiation involved.

Helium is also used in blimps, where the combination of being lighter than air and nonflammable makes it much safer than hydrogen as demonstrated in the explosion of the Hindenburg.

It is also used in deep-sea diving, since helium is less soluble in the bloodstream than nitrogen, and reduces the risk of the diver suffering nitrogen narcosis, high pressure nervous syndrome HPNS , or the bends.

Breathing helium gas causes the voice to become higher pitched because helium is less dense than air, changing the frequency of the sound waves generated in the larynx. Neon is a colorless, odorless, unreactive gas which liquefies at Neon was discovered in by Sir William Ramsay see entry on Argon below and his assistant Morris Travers while working with a sample of krypton. The name comes from the Greek word for "new," neos.

It is found in the Earth's crust at a concentration of 70 ppt, making it the 80th most abundant element; it is found in the atmosphere at a concentration of 18 ppm by volume. Neon which is used commercially is extracted from liquid air by fractional distillation. Neon is used primarily in neon lights ; stimulating neon with electricity causes it to emit an intense red light. Other noble gases are used in "neon lights" as well, to produce different colors.
