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: 8 ...

Noble gases (far right on the periodic table) have closed shells of electrons, which is why they are nearly inert. 7. How are the elements formed? Most elements in the periodic table were formed ...

The first 117 elements on the periodic table were relatively normal. Then along came element 118. Oganesson, named for Russian physicist Yuri Oganessian (SN: 1/21/17, p. 16), is the heaviest ...
