The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

Why has the periodic table endured for 150 years? It’s an amazing tool that can compress a huge amount of information into one format. It’s one of the first things people learn about chemistry.

The periodic table stares down from the walls of just about every chemistry lab. The credit for its creation generally goes to Dimitri Mendeleev, a Russian chemist who in 1869 wrote out the known ...

It seems as if the makeup of the periodic table would be as rudimentary as apples falling down, not up. There’s evidence for elements like oxygen, iron, and silicon all around.

Is It Time to Upend the Periodic Table? The iconic chart of elements has served chemistry well for 150 years. But it’s not the only option out there, and scientists are pushing its limits.

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 ...
