The electronic configuration of Fe(II) ion is [Ar] 3d6

the verdict
COMMON KNOWLEDGE
Legacy classification; evidence review pending
Recorded sources
no sources on either side

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the electronic configuration of Fe(II) ion is [Ar] 3d6?

The electronic configuration of a neutral iron atom is [Ar] 3d6 4s2, so losing two electrons to form the Fe(II) ion leaves the valence configuration as [Ar] 3d6. This is a matter of basic definition in inorganic chemistry and does not require citation.
