All are endothermic

Vedclass · Answer

(D) The addition of an electron to an atom is generally exothermic,but it becomes endothermic if the atom has a stable electronic configuration.$Ne$ $(1s^2 2s^2 2p^6)$ has a stable noble gas configuration.$N$ $(1s^2 2s^2 2p^3)$ has a stable half-filled $p$-orbital configuration.$Be$ $(1s^2 2s^2)$ has a stable fully-filled $s$-orbital configuration.Since all three elements have stable electronic configurations,adding an electron to them requires energy,making all these processes endothermic.

Which of the following processes is endothermic?
