A longstanding mystery of the periodic table involves a group of unique elements called lanthanides. Also known as rare earth ...

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.

One of the rarest and most mysterious elements in the periodic table has finally given up some crucial chemical secrets, eight decades after its discovery. Researchers at Oak Ridge National ...

He suggests instead using a “circular form” of the periodic table. His ‘table’ has seven layers, which are each divided into 18 sectors. These sectors each represent the groups in the original table.

Found at the heavier end of the periodic table, the lanthanides are the first elements to carry electrons in their 4f orbitals. Chemical dogma suggests that these orbitals are not keen on forming ...

HOUGHTON, Mich.--Physicists at Michigan Technological University have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 ...

Last week, we explored the evolution of the periodic table, with all its elements in order. Now that we’re well-organized, let’s dive into the reasoning.

Promethium is the most elusive member of the lanthanide family, a row of 15 metals marooned in the periodic table’s southern territories. Discovered in 1945, ...

The Periodic Table of Elements is a testament to the many millennia of human exploration of the chemical world. However, not everything is known about the elements that appear in its colored and ...
