The first shell in a Bohr model can hold a maximum of 2 electrons.
A model that illustrates the arrangement of electrons in an atom is the Bohr model or the quantum mechanical model. These models depict the distribution of electrons in different energy levels or orbitals around the nucleus of an atom. Each model helps visualize the structure of an atom and how electrons occupy specific regions around the nucleus based on their energy.
Neil Bohr discovered that each electron shell has specified energy levels and limited place for electrons.
The Bohr model
The Bohr model for argon is based on the concept that electrons orbit the nucleus in discrete energy levels. In argon, with 18 electrons, the electrons fill the available energy levels starting from the lowest energy level first according to the Aufbau principle. The Bohr model helps in understanding the arrangement of electrons in an atom and predicting its chemical behavior.
Niels Bohr, a Danish physicist, proposed the concept of electrons orbiting around the nucleus in his atomic model known as the Bohr model. This model was a significant advancement in understanding the structure of atoms and laid the foundation for modern quantum mechanics.

In Bohr's model, electrons in an oxygen atom occupy specific quantized energy levels called shells. Oxygen has two electrons in its innermost shell (K shell) and six electrons in its second shell (L shell). These electrons are arranged in a way that follows the principle of filling the lowest energy levels first before moving to higher ones.
Bohr model consists only one shell.(a hydrogen atom shell) But shell can be increased by exciting the atom. When the electron comes to its shell it loses energy,therefore,different types of regions have been observed i.e,(Lyman,Balmer,Paschen,Bracket and Pfund)
well the first shell can only contain 2 electrons then in the second shell and up you can have up to eight that is how it goes
Bohr diagrams are useful models to show the count - and loosely, the arrangement - of electrons by shell.
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.

The Bohr model for beryllium is a simplified representation of a beryllium atom where electrons orbit the nucleus in circular orbits at specific energy levels. In this model, beryllium has four electrons arranged in two energy levels or shells, with two electrons in the inner shell and two in the outer shell. The Bohr model helps to explain the electronic structure and properties of beryllium.
The Bohr model of the atom places electrons in orbits or "shells." Elements in the first period only have electrons in the first shell. Elements in the second period have electrons in the first two shells. Elements in the third period have electrons in the first three shells, and so on.
Bohr's model of aluminum consists of a nucleus with 13 protons and an appropriate number of neutrons, surrounded by three electron shells. The first shell holds 2 electrons, the second shell holds 8 electrons, and the third shell holds 3 electrons. This configuration reflects aluminum's atomic number and electron distribution.
