Interim Report: Najderek Periodic Table
The Najderek Periodic Table demonstrates 7 periods of chemical elements, like several
other alternate tables. It is color coded to visually distinguish the blocks and each triangle
contains the atomic number and symbol. The table is read vertically. The advantage of this table
is the arrangement of periods (follows quantum chemistry), which generally does not limit the
number of elements or the number of periods. Theoretically, the number of periods is unlimited.
The Najderek table has an "open and condensed structure", because any number of chemical
elements can be incorporated and f-block elements (lanthanides and actinides) are listed in their
periods (6 and 7). So there is no need to list them in separate tables outside periods. Next,
orbitals can be identified in each sub-shell or block (which incorporates 2 elements). And lastly,
this table has been designed to achieve maximum differentiation in the location of the elements,
but simultaneously obtain its minimum energy (which is reflected in the arrangement of double
periods).
