Question

A The expected electron configuration for copper should be [Ar]4s^2 3d^9. However, copper's electron configuration is [Ar]4s^1 3d^10. Which of the following would provide experimental evidence of copper's exception to the normal electron configuration? The mass spectrum of copper shows the different isotopes of copper. Copper ions in solution have color, which indicates that there are unpaired d orbital electrons. The photoelectron spectroscopy spectrum for copper shows the relative number of electrons in each orbit. Copper has the ability to form cations of plus one and plus two, whereas the other transition elements generally form cations of plus two and plus three.

Explanation / Answer

(C) The photoelectron spectroscopy spectrum for copper shows the relative number of electrons in each orbit.

Because. the peaks and height of the photoelectron spectrum is depend on the numberof electrons in each orbital.
