The " inert " or noble chemical elements ( helium, neon, argon, krypton, xenon and radon ) are composed of lone atoms as their smallest discrete unit, but the other isolated chemical elements consist of either molecules or networks of atoms bonded to each other in some way.

All but a few of the most inert elements, such as noble gases and noble metals, are usually found on Earth in chemically combined form, as chemical compounds.

* Dry distillation or destructive distillation, despite the name, is not truly distillation, but rather a chemical reaction known as pyrolysis in which solid substances are heated in an inert or reducing atmosphere and any volatile fractions, containing high-boiling liquids and products of pyrolysis, are collected.

Moisture affects explosives adversely by acting as an inert material that absorbs heat when vaporized, and by acting as a solvent medium that can cause undesired chemical reactions.

Electric propulsion systems use an external source such as a nuclear reactor or solar cells to generate electricity, which is then used to accelerate a chemically inert propellant to speeds far higher than achieved in a chemical rocket.

" Neon is chemically inert and forms no uncharged chemical compounds.

Rhodium ( ) is a chemical element that is a rare, silvery-white, hard, and chemically inert transition metal and a member of the platinum group.

It is inert to most common chemical reactions, such as combustion, because the outer valence shell contains eight electrons.

In an attempt at a chemical conception of the Aether, he put forward a hypothesis that there existed two inert chemical elements of lesser atomic weight than hydrogen.

The members of this group are usually inert to most common chemical reactions ( for example, combustion ) because the outer valence shell is completely filled with eight electrons.

In 1962, laboratory chemists produced the first compound of the inert noble gas xenon, opening up a new field of chemical bonding research.

The noble gases were previously known as inert gases because of their perceived lack of participation in any chemical reactions.

An inert gas is a gas which does not undergo chemical reactions under a set of given conditions.

Because of the non-reactive properties of inert gases they are often useful to prevent undesirable chemical reactions from taking place.

Nitrogen is often used as an inert gas in the chemical industry.

Gold was long popular as a medium of exchange and store of value because it was inert, was convenient to move due to even small amounts of gold having considerable value, had a constant value due to its special physical and chemical properties, and was cherished by men.

Fluoropolymers are advantageous as binders due to their high density ( yielding high detonation velocity ) and inert chemical behavior ( yielding long shelf stability and low aging ).

Only for an external electrical potential ( i. e. voltage ) of correct polarity and sufficient magnitude can an electrolytic cell decompose a normally stable, or inert chemical compound in the solution.

Inert in scientific terminology means ‘ not readily reactive with other elements ; forming no chemical compounds or something that is not chemically reactive .’ An inert fuel tank is non-combustible.

Argon gas is the most common gas used in HIP because it is an inert gas, thus prevents chemical reactions during the operation.

The buffer solution is a dense, inert, aqueous solution which is designed to suspend the sample in a liquid medium without damaging it through chemical reactions or osmosis.

This is because noble gases such as xenon and krypton are highly inert and do not usually form chemical compounds.

In the first trial an inert substance was disseminated from a boat travelling some ten miles off shore under appropriately selected meteorological conditions.

Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature.

Reactions with chalcogens are highly exothermic ( release energy ); the reaction with oxygen or air occurs at room temperature, and therefore barium is stored under oil or inert gas atmosphere.

Similarly, it must be handled under inert atmosphere such as argon.

Unlike lithium and sodium, however, potassium should not be stored under oil for longer than 6 months, unless in an inert ( oxygen free ) atmosphere, or under vacuum.

The switch has a set of contacts inside an evacuated or inert gas-filled glass tube which protects the contacts against atmospheric corrosion ; the contacts are made of magnetic material that makes them move under the influence of the field of the enclosing solenoid.

The market for sodium is volatile due to the difficulty in its storage and shipping ; it must be stored under a dry inert gas atmosphere or anhydrous mineral oil to prevent the formation of a surface layer of sodium oxide or sodium superoxide.

The metallic appearance of a sample can be preserved by sealing it under an inert gas such as argon.

Using greases specifically designed for this purpose is also a good idea, as these are often better at sealing under vacuum, thicker and so less likely to flow out of the taper, become fluidic at higher temperatures than Vaseline ( a common substitute ) and are more chemically inert than other substitutes.

Similarly, Pearling involves surgical insertion of small, inert spheres under the skin along the shaft of the penis for the purpose of providing sexual stimulation to the walls of the vagina.

First, the sample is brought to the desired test temperature under an inert atmosphere, usually nitrogen.

Close examination of Thread ovoids under inert conditions ( near-vacuum pressures and subzero temperatures ) reveal an ice shell embedded with cometary matter ( rocks and dirt ), requiring special glass tools to cut.

Following the patch, a flavored lollipop of fentanyl citrate mixed with inert fillers was introduced under the brand name of Actiq, becoming the first quick-acting formation of fentanyl for use with chronic breakthrough pain.

For example, molecular nitrogen is inert under ordinary conditions, existing as diatomic molecules,.

The term inert gas is context-dependent because nitrogen gas and several of the noble gases can be made to react under certain conditions.

Historical documents may also be stored under an inert gas to avoid degradation.

At the bench scale, chemists perform experiments on air-sensitive compounds using air-free techniques developed to handle them under inert gas.

Measurements may be carried out in air or under an inert gas ( e. g. nitrogen or helium ).

However, after several hours under pressure, divers ' bodies become saturated with inert gas, and no further uptake occurs.

The colorless stones produced strong fluorescence and phosphorescence under short-wavelength ultraviolet light, but were inert under long-wave UV.
