For this article, GOBankingRates defined “expensive” by the quoted stock price. The most expensive stock in terms of the stock price is an A share of Berkshire Hathaway (NYSE: BRK.A). This ...
Earlier this month, the S&P 500 hit a record high of more than 6,000 for the first time ever. Based on that, you might assume that stocks may be too expensive to buy right now as the average stock ...
The intermolecular force between noble gas atoms is the very weak London dispersion force, so their boiling points are all cryogenic, below 165 K (−108 °C; −163 °F). [ 2 ] The noble gases' inertness , or tendency not to react with other chemical substances , results from their electron configuration : their outer shell of valence ...
Argon is the cheapest alternative when nitrogen is not sufficiently inert. Argon has low thermal conductivity. Argon has electronic properties (ionization and/or the emission spectrum) desirable for some applications. Other noble gases would be equally suitable for most of these applications, but argon is by far the cheapest.

A-25 (25% argon/75% helium) is used for nonferrous base when higher heat input and good weld appearance are needed. A-50 (50% argon/50% helium) is used for nonferrous metals thinner than 0.75 inch for high-speed mechanized welding. A-75 (75% argon/25% helium) is used for mechanized welding of thick aluminium. Reduces weld porosity in copper. [14]
Argon is far more narcotic (about 2.3 times more) than the cheaper and more readily available nitrogen at depth, so it loses out to nitrogen in all roles as a primary breathing gas. If the maximum operating depth for air owing to narcosis is taken to be 40 metres (130 ft), then for 20% argox (20% O 2 , 80% Ar) it would be 14.5 metres (48 ft).
Argon compounds, the chemical compounds that contain the element argon, are rarely encountered due to the inertness of the argon atom. However, compounds of argon have been detected in inert gas matrix isolation, cold gases, and plasmas, and molecular ions containing argon have been made and also detected in space.
