I've been studying undergraduate level quantum chemistry, and I have a quick question. (Feel free to make the answers as mathematical as you want)(adsbygoogle = window.adsbygoogle || []).push({});

In the helium atom, does an individual wavefunction describe the state of a single electron, or the system in general (given an arbitrary but allowed energy level)? If it describes the entire system, how can the probability interpretation of the wavefunction be used?
