Question

The actual electronic configuration of chromium and copper slightly differ from expected electronic configuration.why?​

Answer 1

Explanation:

In some cases it is seen that electronic configuration is slightly different from the arrangement given by Aufbau principle. A simple reason behind this it that half filled and full filled subshell have got extra stability. ... Half filled or completely filled orbitals are more stable than those with one electron less.
