Professor Organic Chemistry Tutor ,thank you for another beautiful video/lecture on Electron Configuration Exceptions in AP/General Chemistry. The two examples are really helpful for all current and future students who are taking AP and General Chemistry. Two other Electron Configuration Exceptions are Molybdenum(Mo) and Silver(Ag). This is an error free video/lecture on KZfaq TV with the Organic Chemistry Tutor.

@UmbraLupis7 Жыл бұрын

The exception is due to purely quantum mechanical effect which isn't intuitive and complicated. It's called spin correlation or spin exchange stabilization. Simply put there is an integral that involves the spin wavefuctions of the electrons as part of the energy of the configuration, having the same spin lowers the overall configuration energy relative to others. Even more simply because of Quantum mechanics hanging out with electrons with the same spin lowers your energy.

Why does the electron jump in Copper? There isn't technically any "open space" there like it is in Chromium...

@lunam11 3 жыл бұрын

The real reason isn't about jumping or having room or stuff ..it is because , it is easier for them to remove a 4s electron and bring it to the 3d subshell, which will give them a half filled or completely filled subshell, creating more stability.

@eternaldreamerofsleep 10 ай бұрын

It’s probably because it’s more stable that way. In Cr and Cu case, the electrons leans towards to being unpaired because of its repulsion(?). maybe
