Answer

Explanation:

Step1: Recall metal - reactivity knowledge

Based on general metal - reactivity trends and periodic table properties.

Step2: Analyze the metals

Dubnium is a synthetic element and highly radioactive, and its chemistry is not well - studied in a traditional reactivity sense compared to more common metals. Niobium and tantalum are in the same group (Group 5) of the periodic table. Reactivity generally decreases down a group for main - group metals, but for transition metals like these, niobium is more reactive than tantalum.

Answer:

Niobium: 1 Tantalum: 2 Dubnium: 3
