Why zeff less than screening effect for copper and zinc
Asked by Debdulal | 29th Aug, 2019, 04:47: PM
Electronic Configuration of Cu-1s2 2s2 2p2 3s2 3p2 4s1 3d10
Electronic Configuration of Zn-1s2 2s2 2p2 3s2 3p2 4s2 3d10
Screening effect in case of Cu and Zn Value of s is high( because of shape of 3d electrons) so Zeff decreases and It is less.
