Only someone who truly knows and understands this, please tell me if the electron configurations are right :
Cobalt= [Ar] 4s^2 3d^7
Gallium= [Ar] 3d^10 4s^2 4p^1
Rhodium= [Kr] 4d^8 5s^1
Lanthanum= [Xe] 5d^1 6s^2
Europlum= [Xe] 4f^7 6s^2
Thulium= [Xe] 6s^2 4f^13
ytterblum= [Xe] 6s^2 4f^14
polonlum= [Xe] 6s^2 4f^14 5d^10 6p^4
Curium= [Rn] 5f^7 6d^1 7s^2
Rutherfordium= [Rn} 5f^14 6d^2 7s^2
