﻿772 Dr. A. C. Orehore on the Construction of 



positive electron, which is the same as that of the hydrogen 

 atom, is determined from the fact that the number of electrons 

 per gram is constant for any substance, equal to 6 x 10 23 

 approximately, together with the approximation that the 

 volume of all the atoms per gram is 10" 12 cubic centimetre, 

 the reciprocal of the aether density. This gives 



fc = -735xlO- 12 cm (61) 



The fundamental constants G>*=%Trs) the angular velocity 

 and frequency of the single electron in the hydrogen atom, 

 are determined from Planck's constant together with the 

 above value of />, to be 



s=-^- h =2-385 xlO 19 , .... (62) 



where h is Planck's constant, 6*5 X 10~ 27 , and^ the electronic 

 charge 4*77 x 10 " 10 . Hence 



a,^ = 15-0xl0 19 . ..... (63) 



The distance between a sodium and a chlorine atom in 

 rock-salt along the edge of a cube is given in a* units in the 

 theory by (41) above. In centimetres this is 



J2m*Zn* 

 / p p' 



z=1 ' 378 £a /*-&■ 



using the value of k 2 in (31) and writing /3* = — -*, c being 



the velocity of light. Equating I to 2*814 X 10 -8 cm., the 

 distance in a rock-salt crystal, we find 



N /im 2 2w 2 = 102 N /PF. .... (65)

The theory gives for sodium P = 23 and for chlorine P' = 35, 

 each being equal to the number of electrons in the atom. 

 Hence for sodium and chlorine atoms 



N /Sm 2 2/i 2 =2895 (66)

The values of the radii of the orbits of the electrons within 

 the atoms, m for sodium and n for chlorine, are measured in 

 a* units, where a* is the radius of the orbit in the single 

 electron atom, hydrogen. We cannot arrive at the theo- 

 retical value of the radical in (66) until this unit is determined
