Transcript : Chemistry in its element: argon Promo You're listening to Chemistry in its element brought to you by Chemistry World , the magazine of the Royal Society of Chemistry.

End promo Chris Smith Hello, this week the element that's so indolent that scientists at one time thought it wouldn't react with anything, but in the chemical world laziness can have its advantages especially if it's super quiet car tyres or a safe chemical with which to pump up your diving suit that you're after.

Here's John Emsley. John Emsley It's lazy, it's hard-working, it's colourless, it's colourful - it's argon! Chris Smith John Emsley unlocking the secrets of the heavier than air noble gas argon. Steve Mylon It's almost never the case where the popular elements are that way because of their utility and interesting chemistry. Argon can also be recovered from the exhaust streams of certain ammonia plants.

Industrial Applications Argon has many different applications in many industries. The most common one is as a shielding gas for arc welding — either in pure form or as part of various mixtures.

Argon is present in some potassium minerals because of radiactive decay of the isotope potassium Routes of exposure: The substance can be absorbed into the body by inhalation. Inhalation risk: On loss of containment this liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when in confined areas. Effects of exposure: Inhalation: Dizziness.

Skin: On contact with liquid: frostbite. Eyes: On contact with liquid: frostbite. Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.

At low oxygen concentrations, unconsciousness and death may occur in seconds without warning. The effect of simple asphyxiant gases is proportional to the extent to which they diminish the amount partial pressure of oxygen in the air that is breathed. Symptoms: The first symptoms produced by a simple asphyxiant are rapid respirations and air hunger. Mental alertness is diminished and muscular coordination is impaired.

Argon is one of the Noble gases. It is a colourless and odourless gas which is inert to other substances. Almost all of the argon found in the atmosphere is radiogenic argon and, in space, the most common argon isotope is argon Most commonly, argon is one of the elements used in the welding industry as it provides an inert atmosphere in which welded metals will not oxidise. However, argon gas can be used in a wide range of industries for a number of applications.

Read on to find out more! Did you know argon is used extensively within the healthcare industry? Argon lasers are used in the treatment of retinal detachment and retinal phototherapy for those who are diabetic; they are also used in surgeries to weld arteries and destroy tumours. The applications for the argon laser system are mainly in the medical field, as it is capable of targeting areas with extreme precision. Cryo-needles are used in the treatment of kidney tumours, and as part of the procedure, they are cooled in during argon cryosurgery.

This means diseased or abnormal tissue is destroyed or removed by freezing.
