The correct sequence of electronic configuration is:
Correct answer: A. 4p 5s 4d 5p 6s 4f 5d
- A. 4p 5s 4d 5p 6s 4f 5d
- B. 4p 4s 4d 5p 5s 5f 6d
- C. 4p 4s 4d 5p 5s 4f 5d
- D. 4p 3s 4d 5p 6s 4f 5d
Explanation
This sequence follows the correct order of filling orbitals according to the Aufbau principle. The orbitals are filled in the increasing order of their energy levels, and this sequence correctly reflects the way electrons occupy these orbitals (4p → 5s → 4d → 5p → 6s → 4f → 5d).

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.
