Bohr notation describes the grouping of electrons within the different periods by orbital shells of an atom. For example, Lead (Pb) is an element in the 6th period, 14th group and has an electron configuration of [Xe] 6s24f145d106p2. Based on electron groupings of those orbitals, lead would have an electron grouping by period of 2 electrons in 1s, 8 in 2s2p, 18 in 3s3p3d, 32 in 4s4p4d4f, 32 in 5s5p5d5f, and 4 in 6s6p for a notation of:
2-8-18-32-32-4
This notation is not based on electron orbital energy level, but instead by the number of electrons in each period. This is significantly different than the filling of electrons by energy level that would actually group and fill the electrons in ascending energy levels:
1s, 2s, 2p3s, 3p4s, *3d4p5s, *4d5p6s, *4f5d6p7s, *5f6d7p
Notice specifically that energy levels for the "d" and "f" orbitals are out of sequence within the orbital levels because of their higher energy states relative to their period level. If grouped this way, the notation would look more like:
2-2-8-8-18-18-26
This notation is very redundant within the first six energy levels and can be confusing when compared with the period levels because of the out-of-sequence orbitals for the 3d, 4d, 5d, 4f, and 5f periods.
Also it is counter-intuitive to the periodicity to the sub-atomic organization within the periods while Bohr notation follows it exactly:
- 2 elements in period 1, 2 electrons in 1st set notation
- 8 elements in period 2, 8 electrons in 2nd set notation
- 18 in period 3, 18 in 3rd notation
- 32 in period 4, 32 in 4th notation
- 32 in period 5, 32 in 5th notation
- 46 in period 6, 46 in 6th notation
- 46 in period 7, 46 in 7th notation
(if you consider all "undiscovered" synthetics in the last two notations)
Bohr notation is a way to represent the electron configuration of an atom by using the atomic number to indicate the number of electrons in each energy level or shell. It simplifies the complex arrangement of electrons in an atom's orbitals by organizing them into energy levels.

Who invented the bohr diagram?
The Bohr diagram was invented by Niels Bohr, a Danish physicist, in 1913. He used this diagram to depict the arrangement of electrons in an atom's energy levels.
Which model of the atom first proposed that electrons orbit the nucleus?
The Bohr model of the atom was the first to propose that electrons orbit the nucleus in fixed paths or energy levels. This model was proposed by Niels Bohr in 1913, and it helped to explain the stability of atoms and the emission of specific frequencies of light.
