Lunar rocks are famously dry. They contain almost none of the volatile elements that easily escape into space, such as ...

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 ...

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 ...

Molecules containing noble gases shouldn’t exist. By definition, these chemical elements — helium, neon, argon, krypton, xenon and radon — are the party poopers of the periodic table, huddling in the ...

Noble gases are notorious for their extreme disinterest in bonding with other elements. For this reason, scientists have had to work hard to force gases such as argon into stable compounds (SN: ...

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, ...
