Dubnium is a chemical element with the symbol Dband 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. Chemistry experiments have provided sufficient evidence to confidently place dubnium in group 5 of the Periodic Table.

How many combinations of the three states of matter are there?
There are three basic states of matter: solid, liquid, and gas. The number of combinations possible from these states is 3! (3 factorial), which equals 6. The six possible combinations are solid-liquid-gas, solid-gas-liquid, liquid-solid-gas, liquid-gas-solid, gas-solid-liquid, and gas-liquid-solid.
