For many years, the very existence of francium was a matter of conjecture. It was Dmitri Mendeleev - the father of the periodic table \- who first theorized that there might be an undiscovered ...

That's why the U.S. presence on the periodic table seems so meager: Just three elements—americium, berkelium, and californium—are named for locations here.

Francium — the 87th element on the periodic table — is a naturally occurring, but incredibly rare, radioactive element. It forms and decays extremely quickly, so it has no practical uses, and ...

It was Dmitri Mendeleev - the father of the periodic table - who first theorized that there might be an undiscovered alkali metal lurking somewhere in the universe with an atomic number of 87.

There are, for instance, nationalistic tilts to the periodic table. Two elements (francium and gallium) are named for France and one each for Japan (nihonium), Germany (germanium) and Poland ...

Given the enormous popularity of the periodic table in chemistry, doesn't it make sense to build a periodic table for biology? Pawan Kumar Dhar visualises the anatomy, the potential pay-offs and ...

To account for this, most periodic tables hive off the elements making up this f-block, putting it below the table, leaving a gap in group 3. Fair enough. But there is debate over which of the ...

Eric Scerri recounts the story of element 87, which after a number of false starts was finally tracked down in France — and named in its honour.

T he 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 ...

A new study lays the groundwork to expand the periodic table with a search for element 120, to be made by slamming electrically charged titanium atoms, or ions, into a californium target.

There you have it. All 118 elements should now be in your inventory. Including the Periodic Table part at the start, this whole thing took us over 200 combinations.
