The chemical symbol for oxygen is O. Makes sense. Calcium gets repped by a Ca. Sounds good. Hydrogen? H. Cobalt? Co. Lithium? Li. With you so far. Lead? Pb. There are actually a few things that help ...

This week's chemical element is flerovium, which has the atomic symbol, Fl, and the atomic number, 114. This element, originally given the temporary name ununquadium, was formally named in 2012 for ...

It happens all over the periodic table. The chemical symbol for lead is Pb. For mercury, Hg. For antimony, Sb. My chemistry teacher in high school cracked up every time she referred to the symbol for ...

For the first time in history, a change will be made to the atomic weights of some elements listed on the Periodic table of the chemical elements posted on walls of chemistry classrooms and on the ...

The International Union of Pure and Applied Chemistry (IUPAC) has confirmed that Lawrence Livermore National Laboratory scientists and international collaborators have officially discovered elements ...
