Noble gases have large positive electron gain enthalpies. Why? |
|
Answer» electron gain enthalpyof an element is the energy released when a NEUTRAL isolated gaseous ATOM accepts an extra electron to FORM the gaseous negative ion i.e. anion . we can denote it by ∆i.e. H . Greater the AMOUNT of energy released is the above process ,higher is electron gain enthalpy of the element. |
