Which electron configuration indicates a neutral transition metal element?

A neutral transition metal element typically has an electron configuration that includes partially filled d-orbitals, which is characteristic of transition metals. These elements are found in groups 3 to 12 of the Periodic Table and often have an electron configuration that can be represented as [noble gas] ns² (n-1)d⁴ to (n-1)d¹⁰, where "n" is the principal quantum number. For example, iron (Fe) has the electron configuration [Ar] 4s² 3d⁶, indicating it is a neutral transition metal with a partially filled d-subshell.
