Here's why:

* Placement on the Periodic Table: Meitnerium (Mt) is a synthetically produced element located in Group 7 (VIIb) of the periodic table, which is the transition metal group.

* Properties: Based on its position and theoretical predictions, meitnerium is expected to have properties typical of transition metals.

* Electron Configuration: Meitnerium's electron configuration suggests it has a partially filled d-orbital, a characteristic of transition metals.

While meitnerium is extremely radioactive and short-lived, its atomic structure and predicted properties classify it as a metal.
