Argon (Ar) - Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Know the Uses of Argon, Chemical Properties of Argon, Atomic Mass of Argon.
Argon, chemical element, inert gas of Group 18 (noble gases) of the periodic table, terrestrially the most abundant and industrially the most frequently used of the noble gases. It is used in gas-filled electric light bulbs, radio tubes, and Geiger count
When nitrogen gas present in the atmosphere is heated using hot calcium or magnesium, a nitride is formed leaving behind small amount of argon as an impurity. It can also be obtained as a by-product while purifying natural gas.Health AspectsThe mixing of argon with air can cause super-...
On the other hand, the IR spectrum of mFP in a nitrogen matrix testifies to the simultaneous presence in this matrix of both the trans conformer and of the higher-energy cis conformer (the OH group pointing toward the fluorine atom), which is stabilized by interaction with the matrix gas ...
Given the above arguments, one would expect that the addition of nitrogen would lead to an increase in the electric field in the positive column of the dc discharge in argon. Indeed, this is exactly what happens at relatively low gas pressures (P~1–2 Torr for a tube radius of R~1–2...
