Electron Atom affinity (eV) Li 0.618 Ве not stable 0.278 В C 1.262 not stable о 1.461 3.401 F Ne not stable No electron affinity is reported for Be, N and Ne, meaning that the negative ion is less stable than the neutral atom. In less than 50 words explain these observations. (1 pt)

Answer 1

Electron affinity is the energy released when an electron is added to a neutral gaseous atom.

No electron affinity is reported for Be, N and he because I Be = 15²25² | Il we add one electron im Be the entra election has to enter into higher energy al orbital whic unstable IN = 1s 2s 2p3 I am extra electron is added I will leads to loss of half filled p orbital and the extra election in to repulsion to nitrogen it stability of the p orbital leads Ne = 15² as apo Neon has complete odlet hence any further addition of election will make it unstable. Hence all of the above discussed thru elements will not show any election affinity as energy is rather being required not released. I
