Elements in the same column in the periodic table (‘homologues’) share similar chemical properties because they have similar electron configurations, with the same number of electrons in their ...

They are the first to be included in the table since 2011, when elements 114 and 116 were added. The first true iteration of the table was produced in 1869 by the Russian chemist Dmitri Mendeleev.

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 ...

Four chemical elements have been formally added to the periodic table, completing the scheme's seventh row. They are the first to be included in the table since 2011, when elements 114 and 116 ...

The 4D Periodic Table of Chemical Elements is an answer to this question, having a geometric structure related to the hypercube, a four-dimensional cube. Professor Haresh Lalvani published his paper ...
