How to write bohrium electron configuration

The electrons of the bohrium atom will be filled in the orbitals following certain rules. Bohrium electron configuration is written following the below steps.

Finding the total shell number (here, Bh has a total 7 electron shell)
Next, orbitals (s, p, d, and f) are written in a sequence of 1s 2s 2p 3s 3p 3d 4s 4p 4d 4f 5s 5p 5d 5f 6s 6p 6d and 7s.
Then, subscripts are assigned according to the number of electrons placed in each orbital following their maximum capacity (maximum capacity of s, p, d & f are 2, 6, 10 & 14 respectively) and also following Hund’s rule.
Finally, the bohrium electron configuration is written in ascending order of the electron shells is 1s²2s²2p⁶3s² 3p⁶3d¹⁰ 4s² 4p⁶4d¹⁰ 4f¹⁴ 5s² 5p⁶ 5d¹⁰ 5f¹⁴6s² 6p⁶ 6d⁵ 7s².

Bohrium electron configuration diagram

The electronic distribution of 107 electrons in bohrium is depicted as 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, and 6d orbitals are filled with a capacity of 2, 2, 6, 2, 6, 2, 10, 6, 2, 10, 6, 2, 14, 10, 6, 2,14 and 5 electrons respectively following Aufbau’s principle. So, the diagram will be

Following this above diagram, the electronic configuration of Bh is written in ascending order of orbital energies as 1s²2s²2p⁶3s² 3p⁶4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s²4f¹⁴5d¹⁰ 6p⁶7s²5f¹⁴ 6d⁵.
