Question 12 here is a sketch of the radial probability distribution of three orbitals: use this sketch to answer the following questions. what is the most likely distance from the nucleus for an electron in orbital b? note: your answer must be within 50 pm of the exact answer to be graded correct. list the orbitals in order of increasing energy: suppose all three orbitals were inner orbitals of an atom. in which orbital would an electron be most effective at screening the charge of the nucleus from the outer electrons? clears your work. undoes your last action. provides information about entering answers.
