1920. No. 2. ON THE X-RAY SPECTRA. 43 



The uncertainty in the case of the 3/-system is partly due to the 

 limited experimental material and partly due to the fact, that the deter- 

 mination of the number of electrons of a ring becomes less definite as 

 we pass outwards from the centre, and finally matters may be more 

 complicated and the identification of lines wore difficult as we pass 

 outwards. 



General Remarks regarding Atomic Constitution. 



§ 17. 



The constitution here given for the A'-, L- and J/-ring will involve 

 some change with regard to the general scheme given in ny previous 

 paper (Fig. 2) with regard to the constitution of the elements. 



The first two rings will be the same as before and the surface 

 systams for elements with atomic numbers lower than 10 [Xc) shold be 

 those given in Paper I. 



The difference comes in at the third ring — , which in Paper I. was 

 given a quantnumber 2, while our present results have given to it a 

 quantnumber 3. If, however, we assume two J/-systems; we may still 

 maiiltain the same tnimhcr of electrons (8) of the tird ring, and it is 

 even possible that the fourth ring may have 10 electrons just as indicated 

 in Paper 1. 



If, on the other hand, we assume only one J/-ring the third ring 

 should be composed of 12 electrons^ and provided this value is the right 

 one, we should have to give up the principle, that a ring once formed 

 inside a surface ring should be maintained with the same number of 

 electrons when we pass to higher atomic numbers; for on account of 

 the periodic properties of the elements we cannot assume that a third 

 ring of 12 electrons has been formed as a surface ring for, if so, the element 

 7'i(.V = 22) should possess a surface ring of 12 electrons and F^^(X=23) 

 a surface ring of one electron, which cannot be assumed. Although our 

 present conception leads to some changes with regard to the constitution 

 of the internal rings, still the periodic variations shown by the properties 

 of the elements indicates that the number of electrons of the surface 

 systems are those given in Paper I. 



In my previous paper I found that the electric conductive capacity 

 ought to vary in about the same way as the quantity:
