Highly excited states for hydrogen like atoms (also called Rydberg states) with nuclear charge Ze are defined by their principal quantum number n, where n >> 1. Which of the following statement(s) is (are) true?

• Correct answer
  A

  Relative change in the radii of two consecutive orbitals does not depend on Z
• Correct answer
  B

  Relative change in the radii of two consecutive oribitals varies as 1/n
• C

  Relative change in the energy of two consecutive orbitals varies as 1/ $n^3$
• Correct answer
  D

  Relative change in the angular momenta of two consecutive orbitals varies as 1/n

Hence, the correct answer is options: 'A', 'B', 'D'.
