Verified Claims: 15

Scientific Sources: 17

Also known as: Db

Summary

Dubnium (Db), element 105, is a synthetic, radioactive element [21]. It does not occur naturally on Earth and is artificially produced [21]. Dubnium is a member of group 5 in the periodic table and is expected to share chemical properties with vanadium, niobium, and tantalum [21].

What it is

Dubnium is a synthetic chemical element with symbol Db and atomic number 105 [21]. It is a radioactive element that is produced artificially [21]. The most stable isotope, dubnium-268, has a half-life of about 16 hours [21].

Public Perception

Anxiety level

Low. Dubnium is primarily encountered in scientific research settings, limiting public exposure and concern.

History

Timeline

1968

The Joint Institute for Nuclear Research (JINR) in Dubna, Soviet Union, claimed the first discovery of element 105 [21].

1970

Lawrence Berkeley Laboratory (LBL) in the United States also claimed discovery of element 105 [21].

1997

IUPAC officially named element 105 as dubnium (Db), after Dubna, the location of the JINR [21].

Science

Key findings

  • Dubnium is a synthetic element that does not occur naturally [21].

  • It is a member of group 5 of the periodic table and is expected to share properties with lighter group members like Tantalum [21], [13].

  • Dubnium's most stable isotope, Db-268, has a half-life of approximately 16 hours [21].

Studies

Chemical Characterization of a Volatile Dubnium Compound, DbOCl3

The formation and chemical characterization of single atoms of dubnium in the form of its volatile oxychloride (DbOCl3) was investigated using gas phase chromatography [5], [12].

Safety status

Dubnium is radioactive and poses a radiation risk. However, due to its synthetic nature and short half-life, it poses minimal risk to the general public [21].

Nuance

Relativistic effects may influence the properties of dubnium, requiring advanced quantum chemistry calculations to complement experimental results [13].
