Russian scientists designed a periodic chart where elements are grouped by atomic radius and electronegativity. Elements that form simple compounds would be grouped together.

In their new version of the periodic table, Allahyari and Oganov arranged the elements only based on their radius and electronegativity properties. " [The] clusters indicate chemistries that are ...

Only a Few Grams of This Element Exist—and Scientists Have Used It to Break the Rules of the Periodic Table Doesn’t “organometallic sandwich” sound appetizing?
