Is argon the first noble gas?
They are all odorless, colorless, monatomic gases with very low chemical reactivity. …
What is the noble gas just prior to argon?
The noble gases are the six elements that make up Group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). At one time, this family of elements was also known as the rare gases.
Is argon a noble gas Yes or no?
Argon is an inert, colorless and odorless element — one of the Noble gases.
What are 5 characteristics of argon?
Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature.
What is the history of argon?
Argon was discovered by Lord Rayleigh and Sir William Ramsay in 1894. It was isolated by examination of the residue obtained by removing nitrogen, oxygen, carbon dioxide, and water from clean air. In fact, air contains less than 1% argon.
How is argon used?
Uses of Argon Argon gas is used in graphite electric burners to prevent the graphite from burning. Crystals of silicon and germanium are grown in the presence of argon. Argon is used to kill pigs humanely if there is an outbreak of some disease on the farm. Occasionally, argon is used to put out fires when it is vital that equipment is not damaged.
How is argon gas made?
Argon can be produced from liquid air by fractional distillation. It can also be produced by heating nitrogen gas from the atmosphere with hot magnesium or calcium. The magnesium or calcium combines with nitrogen to form a nitride: A little argon always occurs as an impurity with nitrogen.
What are the noble gases?
Noble gas. The noble gases make a group of chemical elements with similar properties: under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium, neon, argon, krypton, xenon, and the radioactive radon.
