548px-Electron shell 105 dubnium
Dubnium
(ˈduːbniəm) is a chemical element in the periodic table that has the symbol Db and atomic number 105.

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.

CharacteristicsEdit

Chemistry experiments have provided sufficient evidence to confidently place dubnium in group 5 of the periodic table.



ValueEdit

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
