Physicists have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 elements known as rare earths. Physicists at Michigan ...

Squeezing All Elements in the Periodic Table: Electron Configuration and Electronegativity of the Atoms under Compression. Journal of the American Chemical Society , 2019; 141 (26): 10253 DOI: 10. ...

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 ...

Predictive power. Gallium. Mendeleev left blank spaces in his original periodic table so that he could properly line up the known elements. Gallium, element 31, was his first gap to be filled, in ...

Elements within the same group exhibit similar chemical reactions and bonding patterns due to their shared valence electron configurations. The periodic table also reveals trends in atomic size ...
