Question

Explain the formation of di positive and tri positive ions and uni negative and tri negative ions with

example​

Answer 1

Answer:

☞ A uni-negative atom, already has one excess electron in its valence shell, which is providing it its negetive charge, now when, another electron is added to the valence shell, it faces repulsion from this already present electron, and thus, some energy is required to add this electron which makes it energy/heat absorbing (endothermic).

☆☞ While a neutral atom, when adding another electron does not face any such repulsions (as its a neutral species), hence, it goes on to achieve noble gas configuration and thus releases energy, to become stable!
