The pair of orbitals that share the same value of principal quantum number:
Correct answer: B. 3dxy and 3dyz
- A. 2s and 3px
- B. 3dxy and 3dyz
- C. ls and 2s
- D. 4f and 5p.
Explanation
Principle quantum number indicates the energy level or shell in which an electron is located.3dxy and 3dyz both have the same energy level or shell,hence same principle quantum numbers.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
