Argon is a gas that's found naturally in the atmosphere, but it has some interesting everyday uses, too. This lesson will teach you about argon and how it's used in different items and to do different jobs. What Is Argon? You're working on a really important homework project that's...
in bioinorganic chemistry. Xenon (Xe) was discovered in 1898 and initially thought to be completely inert. Its atomic number is 54 and it is a member of the noble gases, non-reactive gases found in Group 18 on the periodic table. It has nine stable isotopes, atoms that have the same ...

The late Frank Lambert contributed greatly to debunking the "entropy = disorder" myth in chemistry education. See his articles Entropy is Simple, and Teaching Entropy. Entropy is still described, particularly in older textbooks, as a measure of disorder. In a narrow technical sense this is correc...
(Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). The first six exist naturally on Earth, but oganesson, which is highly radioactive, has only been synthesized in a lab. It wasn't even discovered until 2002, and it's currently the heaviest known element in the ...
