Q13: Orthogonality of hydrogen wave functions
Consider the following statement: The orthogonality of two wave functions φnlm and φn’l’m’ implies that at any point of space φn’l’m’ has to be zero in this point if φnlm is different from zero in this point and vice versa. A. Correct. B. Incorrect.

Which properties do you expect for the probabilities of finding the electron at a distance r from the nucleus (and
therefore for the wave functions) for different different n and l?
