Chemistry experiments have confirmed that dubnium behaves as the heavier homologue to tantalum in group 5. The chemical properties of dubnium are characterized only partly. Source: Internet
Experimental chemistry The chemistry of dubnium has been studied for several years using gas thermochromatography. Source: Internet
For this group, +4 and +3 states are also known for the heavier members and dubnium may also form these reducing oxidation states. Source: Internet
