For which of these elements would the first ionization energy of the atom be higher than that of the diatomic molecule?
IP He < IP He2: 1σ*>1s (He2 does not exist)
IP N > IP N≡N σ3<2p IP Li > Li2 2sσ<2s IP F < F2 π* > 2p
If you don’t know the meaning of the symbols then you shouldn’t be asking this question
that involves 2nd yr MO theory.
Hmm, in case you meant element as in count then the “air” answer isn’t a factor. in case you meant as in the 4 elementals, then common adequate – alongside with hearth water and earth. Silicone isn’t a factor, silicon besides the shown fact it particularly is. For me, i could elect Strontium as a results of fact it makes the excellent pink color in fireworks (Strontium nitrate)
Helium would have the greater first ionisation enthalpy coz already it have the stable electronic configuration ..
