How does the filling of electrons in f block elements take place ? Pls explain how to write the electronic configuration if f block elements like Gd(64) ? Why its outer electronic configuration is 4f[7] 5d[1] 6s[2] not 4f[8] 5d[0] 6s[2] if (n+l) rule is followed? . Pls explain how to write the electronic configuration of f block as well as d block elements .
