About Bohrium

Bohrium is a chemical element with the symbol Bh and atomic number 107, meaning every atom has 107 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 270 atomic mass units (u).

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

Uses of Bohrium

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

Electron Structure of Bohrium

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), Bohrium has 6 electron shells, with an approximate arrangement of 2, 8, 18, 32, 32, 15 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.
