Shape of orbital is determined by _ quantum number:
Correct answer: D. I
- A. n
- B. m
- C. s
- D. I
Explanation
The shape of an orbital is described by the azimuthal quantum number or orbital angular momentum quantum number (l). The azimuthal quantum number defines the shape of the orbital and determines the subshell to which the orbital belongs. It specifies the angular momentum of the electron in the orbital and governs the three-dimensional shape of the orbital.

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.
