Answer:

In chromium, the 4s subshell is completely filled whereas the 3d subshell is either half-filled (or) completely filled. ... Due to the interelectronic repulsions one electron present in 4s enters to 3d subshell. We can write stable electronic configuration of copper is written as 1s22s22p63s23p63d104s1.
