Q. (3) Which of the following statement is correct? (8.0分) A The solution to Schrödinger’s equation for the hydrogen atom yields a set of wave functions called orbitals. B An orbital (in quantum mechanical model, which describes electrons in terms of probabilities) is not the same as an orbit (the Bohr model, which visualizes the electron moving in a physical orbit, like a planet around a star). C The motion of the electron in an atom cannot be precisely determined. D All are correct.
