The electronic configuration of Fe 3+ is :
Correct answer: C. [Ar]3d54s0
- A. [Ar]3d54s1
- B. [Ar]3d64s0
- C. [Ar]3d54s0
- D. [Ar]3d64s2
Explanation
Fe(Z=26)=[Ar]3d6As2 Fe3+ (23 electrons) = [Ar]3d5

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.
