Identify the ions that correspond to the following electron configurations: (enter your answer with the symbol, numerical charge and sign with no spaces, for example O2-)
doubly positive ion with the electron configuration {Xe}4f^14 5d^10 6s^2 = ?
4+ ion with the electron configuration {Xe} 4f^14 5d^10 = ?
For the first one I got La2+
For the second one I got Po 4+
Am I correct?
