Electron Configuration Of Copper And Chromium
1s 2 2s 2 2p 6 3s 2 3p 6 3d 10.
Electron configuration of copper and chromium. This chemistry video tutorial covers exceptions in electron configuration using the examples of chromium and copper. Therefore one of the 4s2 electrons jumps to the 3d9. Correct electron configuration for copper cu half filled and fully filled subshell have got extra stability. I have started studying chemistry and i was told to memorise the exceptional electronic configurations of chromium and copper.
For the cu ion we remove one electron from 4s1 leaving us with. 1s2 2s2 2p6 3s2 3p6 3d10 4s1. Transcript there are two main exceptions to electron configuration. This give us the correct configuration of.
This happens with nb and ag which are underneath cr and cu respectively.
