1. In a photoelectron spectroscopy experiment Ar is ionised, i.e. an electron is removed from one of the single electron orbitals into the vacuum. An Ar+ ion remains behind. Write down all possible electron configurations and corresponding terms of the resulting Ar+ ion (assuming that the...

Is it maybe referring to the 1s2 2s2 orbitals as the two electrons have the same state with the exception of spin? If a mod feels this should be in advanced physics feel free to move :)

1. "i.e an electron is removed from one of the single electron orbitals into the vacuum." I know what orbitals are but I don't know what constitutes single-electron orbitals. I first assumed it was simply an orbital which in a given configuration only had one electron but that had to be ruled...
