Dubnium (Db)

About Dubnium

Dubnium is a chemical element with the symbol Db and atomic number 105, meaning every atom has 105 protons in its nucleus. It is classed as Transition metal and is a solid at room temperature (estimated, never measured directly because this element decays within seconds). Its atomic mass is about 268 atomic mass units (u).

On the periodic table, Dubnium sits in group 5, period 7, which determines how many electron shells it has and how it tends to react with other elements.

Uses of Dubnium

In daily life and industry, Dubnium is used for Research. These uses are closely tied to the typical properties of elements in the Transition metal category.

Electron Structure of Dubnium

Using a simplified electron shell model (at most 2 electrons in the first shell, 8 in the second, 18 in the third, and so on), Dubnium has 6 electron shells, with an approximate arrangement of 2, 8, 18, 32, 32, 13 electrons from the innermost shell to the outermost. This is a simplified learning model, not the full electron configuration that accounts for the s, p, d and f subshells.
