1. The problem statement, all variables and given/known data Q18. Which of the following statements about Schrodinger equation is true? A) The exact solution of the equation never exists B) It is only applicable to the hydrogen-like atoms C) We can know the energy of the atomic orbital by solving the equation D) The square of the equation gives the probability of finding an electron Answer: C 2. Relevant equations Schrodinger equation 3. The attempt at a solution I do not understand the answer why is not D. "The atomic orbital, when squared, describes the probability of finding the electron at a spatial location; Therefore, an atomic orbital is simply the probability amplitude function. ( |Y(x,y,z)|2; Born’s rule, 1926 ) " Isn't Born's rule applicable in the question? Thanks.
