Quantum Periodic Table

Shriya Tiwari & D. K. Awasthi, Quantum Periodic Table, wjpmr, 2021, 7(4), 124-130

The authors write:

"In [the] quantum periodic table, The elements are arranged according to the order of electron-shell filling, by classifying the energy levels of the atoms in the order they are filled, to create a layout based on electronic configuration. The classification of the elements is done purely on the basis clarified above, without giving any weight age to the atomic numbers. With the advent of electronic configurations and quantum mechanics, many attempts have been tried in this periodic table to unlock all the problems related with the placement of elements, which have been remained as the topic of debate by generations of chemists."
