The filling of the 3d electron subshell beginning around scandium is a standard chemical principle governed by the relative energy levels and ordering of atomic orbitals.

The analysis

The claim refers to the standard filling order of the periodic table where 3d orbitals begin filling at scandium due to energy level hierarchies. Papers [2] and [6] provide relevant atomic physics and quantum-chemical background on the electronic structure and orbital states of scandium and other 3d transition metals. No papers refute the claim.
