WebAbove this line is the region called "free electrons" in the diagram. This corresponds to an ionized atom. In this range, the energy levels are not quantized -- that is, any energy is possible. So any photon with enough energy to put the total energy somewhere in that shaded region is capable of ionizing the atom. WebThe energies of electrons in molecular orbitals can be observed directly by measuring the ionization energy. This is the energy required to remove an electron, in this case, from a molecule: (1) H 2 ( g) → H 2 + ( g) + e − ( g) The measured ionization energy of H 2 is 1488 kJ mol -1. This number is primarily important in comparison to the ...
