Tools of construction of system of elements.
www.genevo.org/B.htmAn old model of atom does not answer many questions about properties. And... I decided to offer you a new one. It is called "ball-bearing model of atom". It is very flexible and it can be twisted!
www.genevo.org/F.htmIt is logical, that shown cyclicity for d-elements is shown also in other families.
http://www.genevo.org/Z1.htmI have tried to simplify last model maximum.
Secondary periodicity see at figure (the schedule of the data).
www.genevo.org/S.htmIn my last work I show secondary periodicity on this property for s-elements on the example of the data on electron affinity. In the same place, on the example of d-elements other logic of the tableis visible, - not periodicity but cyclicity.
Some properties are cyclic and not correspond to the periodic table.
I offer to your attention
http://www.genevo.org/H.htm It is visible on the schedule that on the property of electron affinity s-elements behave variously before p and d-elements . Before ? - elements electron affinity grows, before d-falls.
Even on this property it is possible to speak about available laws which are not clear yet.
Secondary periodicity is connected with repeated filling of everyone
orbital by the second electron and with relative positioning of orbitals.
Secondary periodicity is more brightly expressed at last families.
Similarity by orbital structure can be various.
Orbitals may be focused in one direction, thus,
electronic configurations of compared atoms may not coincide.
