Other people have been known to have sodium parties too—MIT students traditionally throw a block of the stuff into the Charles River every year during homecoming. What sets Gray and his element ...

The International Union of Pure and Applied Chemistry (IUPAC) has announced that four new elements — with atomic numbers of 113, 115, 117, and 118 — will be added to the periodic table.

Online educators have developed an interactive periodic table that presents the various practical applications of each element. Their goal is to make understanding these elements easier for everyone.

The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...

In the past 250 years, new elements have been added to the table about once every 2 ½ years on average, said Paul Karol of Carnegie Mellon University. He chaired the committee that recognized the ...

Elements in the periodic table are arranged in order of increasing atomic number. The atomic number represents the number of protons in an atom's nucleus, uniquely identifying each element. For ...

The periodic table captures a subtle pattern that runs through the chemical elements , the fundamental building blocks of everything around us: from the aluminium in bike frames to the xenon gas ...

The result is a table that allows a person to both easily scan the weight of elements and guess at how they will react with other elements on the table. So we know that chemically, sodium (symbol ...
