Additon of an electrons to a uninegative ion (except to VI A group elements) is an endotherimic process whereas the formation of uninegative ion from its neutral atom is an exothermic process comment |
| Answer» Solution :Addition of an electron to unine gative ioninvolveds repulsion between the electron and negatively chargedion so energy is REQUIRED to add and ELECTON to a uninegative ion hence it is endothemic process when an electorn is aded to a NEUTRAL aotm it workd towards the force of attraction exertied by the nucleus of the neutral atom and hence energy is releaaed during this process | |
