Dubnium is a solid metal at room temperature. Though the color is unknown, scientists predict that it is a grayish black, or silver. Dubnium is a good conductor of electricity and thermal energy, but has no known uses. |

Interesting Facts and History:
Dubnium was created by smashing two other particles, Californium and Nitrogen, together in a particle accelerator. When these two elemental particles collided with such force, they could not stay together as a mixture, and they formed a new compound, Dubnium. Some of the energy in this transaction was converted into thermal energy Dubnium is so unstable that it disappears in about 4.2 seconds, for it burns when in contact with air. Scientists have no yet been able to posess pure Dubnium; it always has a couple impurities, so scientists have never been able to run tests on pure Dubnium. Dubnium used to be called Hahnium (Ha), but the name was changed by a comittee of scientists in 1970. Even to this day, people forget about the name change, and call it Hahnium. It was discovered by Albert Ghiorso and a team of Russian scientists. The element is named after Dubna, Russia.
