Aufbau principle cannot tell us about?
Correct answer: A. The no. of electrons in valence shell.
- A. The no. of electrons in valence shell.
- B. Relative energies of shells.
- C. Relative energies of subshells.
- D. Distribution of electrons in orbitals.
Explanation
The Aufbau principle provides information about the order in which electrons fill atomic orbitals, but it does not explicitly specify the number of electrons in the valence shell,so option 'A' is the correct answer.

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.
