Quantum numbers specify the --------- of electrons.
Correct answer: D. All of these
- A. Shape
- B. Energy
- C. Position
- D. All of these
Explanation
Quantum numbers specify different properties of electrons in an atom. Specifically, the four quantum numbers (principal, azimuthal, magnetic, and spin) specify the energy, shape, orientation, and spin of an electron, respectively.The principal quantum number (n) specifies the energy level or shell of the electron.The azimuthal quantum number (l) specifies the shape of the orbital (s, p, d, f) and is related to the angular momentum of the electron.The magnetic quantum number (m) specifies the orientation of the orbital in space.The spin quantum number (s) specifies the spin of the electron.Therefore, quantum numbers specify the energy, shape, position, and spin of electrons in an atom.

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.
