Which elements are inactive gases

While chemical inertness and biological inertness are often the same, sometimes a substance can be one and not the other. For example, while xenon does not chemically react in the human body, it nonetheless has biological effects that have been exploited for anesthesia as well as improvement of tissue damage caused by inadequate blood supply ischemia.

Inert materials are good choices for chemical containers. For example, acid waste should not be stored in metal drums because these will quickly corrode. However, glass or polyethylene containers are inert to most acids. If a chemical spill occurs, one may need to clean up the spill by using an inert absorbing material such as vermiculite or sand.

The Safety Data Sheet will usually recommend a specific material, but not always. Assuming your SDS was created using the format required under HCS , spill cleanup information will be found under Section 6 accidental release measures. But be sure to read the rest of the sheet as well, because it's important that you know the physical properties of the material, the health hazards, incompatibilities etc.

Safety Emporium has a great lineup of gas cylinder signs, storage racks, clamps and more. These are used as oxidizing agents. The noble gases glow in distinctive colors when used inside gas-discharge lamps, such as neon lights. Xenon is commonly used in xenon arc lamps, which are present in film projectors and automobile headlights due to their nearly continuous spectrum that resembles daylight.

The noble gases are also used in excimer lasers, which are based on short-lived electronically excited molecules known as excimers. These lasers produce ultraviolet light, which, due to its short wavelength nm for ArF and nm for KrF , allows for high-precision imaging.

Excimer lasers have many industrial, medical, and scientific applications. They are used for microlithography and microfabrication, which are essential for integrated circuit manufacturing; and for laser surgery, including laser angioplasty and eye surgery.

Argon which is used commercially is extracted from liquid air by fractional distillation. Argon had been observed before by Henry Cavendish in , but it had not been identified as an element.

Because of its unreactivity, it was named for the Greek word for "idle," argos. When argon was discovered, it didn't fit with the reactivities of any other element on the periodic table, and chemists realized that there might be a whole family of previously-unrecognized elements, which we now recognize as Group 8A.

Argon is used in light bulbs because it is inert to the hot metal of the bulb filament; the filament would burn out much faster in air or even pure nitrogen. It is also used in metal refining, some "neon" lights argon produces a blue light , some food packaging to provide an inert atmosphere to reduce spoilage , in the tires of some luxury cars in place of air, and in lasers used in eye surgery.

Argon is produced by the radioactive decay of potassium; the potassium nucleus undergoes electron capture to produce the stable argon nucleus.

The ratio of potassium to argon in some rocks can be used to determine the age of the rock. Recently, the first argon compound, argon fluorohydride HArF , was reported , which is stable up to 27 K. I'm waiting for hydrogen to be replaced by boron: I think a molecule that spells out "BArF" would be worth investigating.

Or not. Krypton is a colorless, odorless, unreactive gas which liquefies at It is found in the Earth's crust at a concentration of 10 ppt, making it the 81st most abundant element; it is found in the atmosphere at a concentration of 1 ppm by volume. Krypton which is used commercially is extracted from liquid air by fractional distillation.

Krypton was discovered in by Sir William Ramsay and his assistant, Morris Travers, in a sample of argon gas extracted from the atmosphere. The name "krypton" is derived from the Greek word kryptos , meaning "hidden" which has nothing to do with the home planet of Superman. Krypton is used in some "neon" lights, producing a violet color when electricity is passed through it. It is used for landscaping and interior design.

Neon is used in parts of aircrafts. Argon is used to create inert atmosphere. It is used for the production of titanium. It is used in welding. It is used in light bulbs to prevent them from corrosion. It is used in tyres of luxury cars to protect tyre and reduce noise on road.

It is used in double-glazed windows. It is used in radioisotope dating. Being an inert gas argon is used in heat treating processes for matters. It is used in 3-D printing. It is used in metallurgy as it prevents oxidation or rusting. It is used in tubes of fluorescent lights. It is used in flash lamps which are used for high-speed photography. It is also used in sign boards. It is used in nuclear fusion energy research experiments. It is used in constructing electromagnetic calorimeters.
