Principal quantum numbers specify the _ of electron.
Correct answer: D. Both B and C.
- A. Shape
- B. Energy
- C. Position
- D. Both B and C.
Explanation
The principal quantum number determines the size of the orbit and the distance from the nucleus. Hence, they determine the position of an electron.

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.
