Periodic Meaningful Symbols for The Chemical Elements

The present symbols of the elements are main abbreviations of names in accordance with a very old tradition. Considering the recent attempts to rationalize the symbols of the elements beyond Z=103, we propose to proceed much further and conceive for every element a meaningful symbol able to predict its properties. For this purpose we refer to the electron structures and feel logical to link the symbol to the valence shell population. The symbol is built with one or two letters whose frame determines the involved valence shells and with right superscript numbers indicating the valence - electron population. Thus, using seven letters only and limited small numbers we could conceive a set of periodic rational symbols. We do not need any more to refer to Latin-Greek roots and even to the periodic table of the elements.
