On the planar periodic table

摘要

We reconsider, in this work, the construction of the two-dimensional (2-D) periodic table. The two-dimensional logarithmic Coulomb system is used to generate atomic shells for the 2-D atoms. A q-deformed model is developed to explain the ordering of the shells predicted by the 2-D Madelung rule. Our model, with the value cl = 1.26 for the deformation parameter, reproduce very well the above rule. We also compute the key function and the address function which, together with our model fur the Madelung rule, permit us to give a new format of the 2-D periodic table. It is shown that this table is different from the one existing in the literature, and we have a new family of elements, the g family. The question of the existence of 2-D "ions" is briefly discussed.
