Many scientists worked on the problem of organizing the elements, but Dmitri Mendeleev published his first version of the periodic table in 1869, and is most often credited as its inventor. Since then ...

Can you name everything from Ac to Zr? Test your knowledge of the periodic table and see if you can top the leaderboard ...

Even after 1870, Meyer and Mendeleev were still unaware of each other’s work, although Meyer later admitted that Mendeleev had published his version first. Meyer did contribute to the development of ...

The actual boiling point of radon is -61.7˚C. An estimate would lie midway between -100˚C and -50˚C based on the shape of the graph.

These are almost one-quarter of the periodic table and are mainly found in the first four periods. Of these, 11 are essential elements that our bodies need in larger amounts: oxygen, carbon ...

A team of researchers has developed a printing technique capable of forming a periodic nano/microstructure on the surface of a polydimethylsiloxane (PDMS) slab and easily transferring it onto the ...

Ram Mohan looks at how bismuth — a remarkably harmless element among the toxic heavy metals in the periodic table — has sparked interest in areas varying from medicinal to industrial chemistry.

To achieve these goals, the team first plans to optimize the experimental conditions under which it can produce various forms of printable periodic nano/microstructures. More information ...
