model depicts a compound of the molecule CUO bonded to four argon atoms.
Chemists at Ohio State University and the University of Virginia created
the first-ever compounds to link uranium to argon, a so-called "noble
gas." The chemists suspect that this is one possible configuration
for such a compound, with four argon atoms circling the center of the CUO
molecule like the spokes of a wagon wheel. Here carbon is black, uranium
is blue, oxygen is red, and argon is pale green. (Graphic courtesy of Ohio
