H-Atom and multi-electron atoms

Postby Beatrice Petelo 1F » Wed Oct 10, 2018 9:12 pm

Is there a reason why we use two different equations for the hydrogen atom and the multi-electron model?

It is necessary to have different equations because during Bohr's experiments, he was able to derive an equation that correctly predicted the various energy levels in the hydrogen atom (which has one electron) which then corresponded directly to the emission lines in the spectrum. However, it failed to explain the electronic structure in atoms that contained more than one electron. If you look at the period table, you will be able to see how many electrons an element has.

yup. Each atom has it's own unique emission line spectrum and the equation was made specifically for hydrogen through finding the its line first and then coming up with an equation that made sense based on experimental data. Not to mention that multiple electrons complicates things a lot because electrons can also effect one another etc.

When we have multi-electon atoms, the shielding effect and the different electrostatic energies that result when you have different numbers of protons impact the performance of the electrons.
