Ionization Energy

Postby Katrina Jang 2H » Sat Oct 31, 2015 12:06 pm

Why would a species have a lower ionization energy when the electron is lost from a higher molecular orbital?

If you think of this answer in terms of the atomic diagram, the the further away the electron is from the nucleus, the easier it is to remove it from the atom. Therefore, when it is in a higher molecular orbital, it is farther from the positive nucleus (repelled further by the electrons other than the one getting pulled away (the electrons in between)), so it requires less energy to remove. Thus, the lower ionization energy. Hope this helps! Try picturing it if this descrption isn't necessarily doing it for you!
