ስለ Dubnium
Dubnium is a synthetic, radioactive transactinide element. Limited experiments show it behaves somewhat like niobium and tantalum, with some unexpected properties.
ፕሮግራሞች
No practical applications. Scientific research only.
ሐቅ
Chemical experiments on dubnium use only a few atoms at a time, yet scientists found surprising deviations from predicted behavior.
