The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom ...

If you were to take every element in the periodic table and order them by how abundant they are in the Universe, you'd find something a little bit surprising. The most common element is hydrogen, ...

Hydrogen and helium formed shortly after the Big Bang. Stars create elements lighter than iron through nuclear fusion. Supernovae produce elements heavier than iron via the r-process. Neutron star ...

What’s going on with this silent threat that can stealthily damage your body in ways that can take years to reveal themselves ...

Four new chemical elements now have official names and symbols, the International Union of Pure and Applied Chemistry (IUPAC) announced this week. After a five-month review, IUPAC chemists have ...

For now, they're known by working names, like ununseptium and ununtrium — two of the four new chemical elements whose discovery has been officially verified. The elements with atomic numbers 113, 115, ...

Earlier this year, the International Union of Pure and Applied Chemistry (IUPAC) accepted the evidence that indicated we had produced four new elements, filling out the bottom row of the periodic ...

Elements heavier than iron, such as gold and uranium, are primarily formed through neutron capture processes, specifically the rapid neutron capture process (r-process). The r-process, unlike the ...
