Consequently, the energy exists before hand in the atoms from which they escape. " J. J. Thomson, Larmor and Lorentz have urged the con- ception that the atom is very complicated, being made up of charged particles, in rapid oscillatory or orbital motion. As the particle is atomic in size, it must be composed of electr...ons in motion. The radio-active elements, therefore, are composed of positively charged particles, whose mass is about that of hydrogen or helium. 12 DAYS Fj g . 4y CURVES SHOWING DECAY OF ACTIVITY OF THE EMANATION AND RECOVERY OF ACTIVITY OF RADIUM (AFTER RUTHERFORD). The curves (see Fig. 47), showing the decay of the activ- ity of the emanation and the recovery of the activity of radium are extremely interesting. It will be noted that they are com- plementary to each other. When the emanation has lost one- half of its activity, the radium has spontaneously regained one- half of its lost activity.
