The Physical Properties of ArgonTHE following measurements may be of interest in connection with the chemical position of argon. The gas was prepared from atmospheric air with the aid of oxygen and alkali only.. 1895 Nature Publishing Groupdoi:10.1038/052293a0RAYLEIGHSpringer NatureNature...
What is the electronegativity of noble gases? What are the properties of argon? Define noble gas configuration. How are noble gases different from most other natural elements? Give examples of noble gas configuration. Why are noble gases chemically inert?

Argon was discovered by a Scottish chemist, Sir William Ramsay and an English chemist, Lord Rayleigh in 1894. However, an English scientist, Henry Cavendish identified the presence of argon 200 years before its discovery when he found a small amount of gas left behind while separating nitrogen ...

The electronic and optical properties of indium zinc tin oxide (IZTO) thin films grown under different gas environments were investigated by means of x-ray photoelectron spectroscopy and reflection electron energy loss spectroscopy (REELS). REELS spectra revealed that IZTO thin films under argon mixed...
The obtained ingots were put into quartz crucible with a 0.5 mm diameter nozzle, induction melted and ejected under a pressure of 0.02 MPa of argon gas onto the high-speed rotating copper wheel with the linear speed of 20 m/s. The melt-spun ribbons were sintered using both hot ...
In the first step, the reaction mixture was stirred for 20 h at room temperature under an argon atmosphere to prepare viscous poly(amic acid). Thereafter, the poly(amic acid) was thermally cyclized at 175 1C for 8 h. After this step, the resultant solution of the polymer was cooled to...
