The Five Solids - Argon pt I & II flac album

A molecular solid is a solid consisting of discrete molecules. The cohesive forces that bind the molecules together are van der Waals forces, dipole-dipole interactions, quadrupole interactions, π-π interactions, hydrogen bonding, halogen bonding, London dispersion forces, and in some molecular solids, coulombic interactions.

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. Argon is the third-most abundant gas in the Earth's atmosphere, at . 34% (9340 ppmv). It is more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv)

Argon's discovery, interesting facts, and properties - plus informative videos and comprehensive data tables. William Ramsay discovered argon when he first saw its spectrum and realized it matched no other’s. Image: NASA, ESA, and the Hubble SM4 ERO Team. Argon was the first noble gas to be discovered. The first hint of its existence came from English scientist Sir Henry Cavendish as far back as 1785. Under normal conditions argon is a gas. ctile are properties of solids, so they don’t really apply to argon. A. Actinium – Aluminum – Americium – Antimony – Argon – Arsenic – Astatine. B. Barium – Berkelium – Beryllium – Bismuth – Bohrium – Boron – Bromine.

Platonic Solids - Why Five? A Platonic Solid is a 3D shape where: each face is the same regular polygon. Simplest Reason: Angles at a Vertex. The simplest reason there are only 5 Platonic Solids is this: At each vertex at least 3 faces meet (maybe more).

Argon has a boiling point of -185. 8 degrees Celsisu, or -302. 5 degrees Fahrenheit. Any temperature above this and it'll be a gas. Unless you have a really, really cold room. k views · View 2 Upvoters. hVB gbZyN MbBGrCoIQEwfOyg. Argon is an inert, noble gas, and is the 3rd most common gas in the earth's atmosphere. It is extremely unreactive, and so is used as a shielding gas for high temperature processes. It is also used in gas discharge tubes, like neon, and it produces a characteristic blue glow.
