Experimentally, we observe that its ground-state electron configuration is actually [Kr]5s 1 4d 4. We can rationalize this observation by saying that the electron–electron repulsions experienced by pairing the electrons in the 5s orbital are larger than the gap in energy between the 5s and 4d orbitals. There is no simple method to predict the ...

The web page you requested is not available due to a glitch. It is part of a free textbook on organic chemistry that covers atomic structure and electron configurations.
The electron configuration of an atom shows the number of electrons in each sublevel in each energy level of the ground-state atom. To determine the electron configuration of a particular atom, start at the nucleus and add electrons one by one until the number of electrons equals the number of protons in the nucleus.
