This is a radioactive synthetic element whose most stable isotope is 268Db with a half life of 28 hours. This is the longest lived transactinide isotope and is a reflection of the stability of the Z = 108 and N = 162 closed shells and the effect of odd particles in nuclear decay.
Chemistry experiments have provided sufficient evidence to confidently place dubnium in group 5 of the periodic table.
The base value of each unit of ranges between 10 and 30Ð per unit, with up to 4 units being found at any one time.
Presence on Mars: Rare
