Chromium exhibit 4s^1 3d^5 electronic configuration instead of 4s^2 3d^4. Explain.
Completely filled or half-filled subshells are highly stable. In 4s1 3d5 configuration, both s and d subshells are half-filled. Thus, due to the extra stability associated with half-filled subshells, chromium exhibits 4s1 3d5 electronic configuration instead of...
