What is the electron configuration for Bohrium (Bh)?

The electron configuration for Bohrium (Bh), which has an atomic number of 107, reflects its position on the periodic table and the order of filling of electron orbitals. In the case of Bohrium, it is located in period 7 and is a transition metal within the d-block of the periodic table.

The correct configuration begins with the noble gas core of Radon, represented by [Rn], which accounts for the first 86 electrons. Following this core, the next electrons fill the 7s orbital, accommodating two electrons, thus contributing 7s². As we move to fill the f-block, the 5f orbital is filled next, with 14 electrons being added, hence 5f¹⁴.

The final step involves filling the d-orbitals. For Bohrium, the 6d orbitals contain five electrons, leading to 6d⁵. This results in the complete electron configuration of [Rn] 7s² 5f¹⁴ 6d⁵, accurately representing the electron arrangement of Bohrium.

Understanding how to read and write electron configurations, especially for heavier elements, is essential in highlighting how orbital filling follows the principles of Aufbau and Hund's rule, as well
