Exempel på hur man kan använda ARGON i en mening

• Nearly all argon in Earth's atmosphere is radiogenic argon-40, derived from the decay of potassium-40 in Earth's crust.
• The noble gases (helium, neon, argon, krypton, xenon, and radon) are also gases at STP, but they are monatomic.
• The noble gases (historically the inert gases, sometimes referred to as aerogens) are the members of group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) and, in some cases, oganesson (Og).
• Neon was discovered in 1898 alongside krypton and xenon, identified as one of the three remaining rare inert elements in dry air after the removal of nitrogen, oxygen, argon, and carbon dioxide.
• mixtures of helium and neon (HeNe), nitrogen, argon, krypton, carbon monoxide, carbon dioxide, or metal vapors; (gas lasers).
• His work in isolating argon, helium, neon, krypton, and xenon led to the development of a new section of the periodic table.
• The possibility of a seventh noble gas, after helium, neon, argon, krypton, xenon, and radon, was considered almost as soon as the noble gas group was discovered.
• The tube is filled with a gas at low pressure, usually mostly neon and a small amount of argon, in a Penning mixture.
• This method involves ball milling of high-purity graphite powders down to an amorphous nanoscale size under an argon atmosphere.
• helium, neon, argon, krypton, xenon, and radon, show an unexpected behaviour when exposed to this new element.
• The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine and argon.
• Generally, all noble gases except oganesson (helium, neon, argon, krypton, xenon, and radon), nitrogen, and carbon dioxide are considered inert gases.
• It is highly reactive with water and is stored usually under hexane or other hydrocarbons, or under an inert gas (usually dry nitrogen or argon) if high purity and low levels of oxidation are required.
• Morris, poetically addressed the transition from the argon lighting to the new LED system, drawing attention to the absence of the green light on the skyline by reproducing the color with the OMNI's lights and musing on the uses of liquid argon.
• In the 1920s, thyratrons were derived from early vacuum tubes such as the UV-200, which contained a small amount of argon gas to increase its sensitivity as a radio signal detector, and the German LRS relay tube, which also contained argon gas.
• Flowing-afterglow mass spectrometry uses a flowing afterglow to create protonated water cluster ions in a helium or argon carrier gas in a flow tube that react with sample molecules that are measured by a mass spectrometer downstream.
• In the event of a fire The National Archives would be clearly unable to use sprinklers for fear of ruining its holdings, and so when the building is evacuated, argon gas is released into the air-tight repositories.
• Noble gases like helium and argon are monatomic, which makes them harder to ionize and tend to have smaller effective diameters.
• Low-pressure sodium (LPS) lamps have a borosilicate glass gas discharge tube (arc tube) containing solid sodium and a small amount of neon and argon gas in a Penning mixture to start the gas discharge.
• Entrained argon – diffused argon that fails to escape from the magma – may again become trapped in crystals when magma cools to become solid rock again.
