The discussion centers around the endothermic nature of the process involved in forming a cation, specifically focusing on potassium cations. Participants explore the relationship between atomic size, energy changes, and ionization energy, questioning why energy is required for ionization.
Participants express differing views on the relationship between size change and reaction heat, indicating a lack of consensus on the topic. The discussion remains unresolved regarding the implications of ionization energy and the endothermic nature of cation formation.
There are unresolved questions about the assumptions underlying the relationship between atomic size and energy changes, as well as the specific definitions of ionization energy and its implications for the process discussed.
the energy we put to pull of the electron ,Borek said:Size change has no correlation with the reaction heat.
Do you know what ionization energy is?
