Web22 nov. 2012 · An atom with 36-fold ionisation absorbed at least 19 photons in this process, thus an energy of more than 28.5 kilo-electronvolts. “This is twice as much as we had expected,” says Benedikt Rudek. The CFEL scientists used the measurements to refine a mathematical model which allows such resonances in heavier atoms to be calculated. WebThe enthalpy of ionisation is determined by the following factors: Nuclear charge: As the nuclear charge increases, the ionisation enthalpy increases proportionally. This is owing to the fact that, as nuclear charge increases, the electrons in the outer shell become more tightly bound to the nucleus, requiring more energy to extricate an ...
