Noble gas chemistry has evolved remarkably since the seminal discovery of xenon compounds in the early 1960s. Once deemed completely inert, noble gases are now known to participate in subtle yet ...
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they ...
The noble gases, which reside on the East Coast of the periodic table, are its aristocrats—detached and aloof, never bothering to interact with the rabble of common elements that make up the vast ...
A NASA/ESA Hubble Space Telescope image released July 7, 2012, shows U Camelopardalis, a star nearing the end of its life located in the constellation of Camelopardalis (The Giraffe), near the North ...
NOBLE gases are so called because, like the nobility, they do nothing. You might also call them rare gases, because they are so rare on Earth as to be nearly non-existent. The one exception is argon, ...
Every first-year chemistry student knows about them nowadays: those chemically dull elements that occupy the far right column of the periodic table. But it wasn't until the end of the 1800s that the ...
Argon was forged in the doomed star that became the Crab Nebula. (Courtesy: NASA, ESA, J Hester and A Loll (Arizona State University)) An international team of astronomers has accidentally spotted the ...
