Bloomberg Businessweek / SEPTEMBER 2, 2019 THE ELEMENTS
By Eric Roston If chemistry were fair, the 118 elements
would distribute themselves evenly among
the 154 million substances in the
American Chemical Society’s
CAS Registry. It’s not. All but
about 2 million have a molecular
scaffolding of atom No. 6, carbon.
It’s the diamond on the ring, and
also a good bit of the finger
wearing it. Here, by size and date of
discovery, are a few mighty molecules
brought to you by the letter C.

Carbon can hold on to things
and let them go, kind of like
Velcro (which is made of carbon,
as it happens). It makes strong
bonds that give molecules such
as proteins and drugs their
shape, and also readily releases
those bonds, letting molecules
emit stored energy. (Think bombs
and carbs.) And carbon’s ability
to maintain four bonds at once
makes it the periodic table’s
architecturalworkhorse.
