Cr: 3d5,4s1..... d orbital has attained half filled stability& even s obrbital is half filled..rather than 3d4 4s2 d orbital is not half filled & is unstable
Cu: 3d10 4s2..... d orbital fully filled & stable also s orbital is half filled rather
than 3d9 4s2
*** any orbital has high stabilty when either empty or half filled or fully filled than any no.of e- in it......
