CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...
