Explain the energy changes inovoled in the formation of f and O^(2) form their respecitive atoms |
| Answer» Solution :Though `F^(-)` and `O^(-2)` are ISOELECTRONIC speices the formation of `F^(-)` is exothemic while `O^(-2)` is endotherimic elemnts (or) IONS having inert gas configuration are highlystable in this process a large amount of energy is released but in the CASE of the formation of `O^(-2)` replusions exist between the added electron and already existingh `O^(-1)` ion .sothis process require supply of energy to overcome this repulsion .HENCE the formatoin of `O^(-2)` is an endothermic process | |
