In the Bohr model of the atom, an electron emits a photon when it moves from a higher energy level to a lower energy level.
In the Bohr model of the hydrogen atom, the electron is assumed to orbit the nucleus in discrete energy levels. The ionization energy of the hydrogen atom corresponds to the energy required to completely remove the electron from its orbit, moving it from its lowest energy level to an unbound state. This energy depends on the specific energy level the electron is in, as each energy level has a corresponding ionization energy.

The Bohr model for sulfur shows that sulfur has 16 electrons in total, with 2 in the first energy level, 8 in the second energy level, and 6 in the third energy level. The electrons in the outermost energy level are involved in chemical reactions.
Remember that Bohr's theory on atomic structure was 1) only a model and 2) cannot truly violate anything, as it was only a model. However, the fundamental flaw in Bohr's model is the assumption that an electron of a certain energy level, or "shell", can only occupy that energy level (unless it jumps to another level, requiring energy). This essentially claims to know the relative position of that electron, while Heisenberg's uncertainty principle states that this is impossible. Rather, the electron cloud model is more commonly used today, which gives regions of probability in which it is most likely to find an electron of a given energy level.
When an electron falls back an energy level, it releases energy in the form of electromagnetic radiation (such as light). This process is known as electron transition or atomic emission, and the energy of the emitted light corresponds to the energy difference between the two energy levels involved.
To draw a Bohr diagram of boron, place 3 electrons in the first energy level and 2 electrons in the second energy level, following the Bohr model's rules of electron distribution. Boron has 5 electrons total, with 3 electrons in the outermost energy level.
The basic assumptions of the Bohr model of the atom are that electrons orbit the nucleus in fixed, quantized energy levels without emitting radiation, electrons can only exist in these specific energy levels, and that energy is absorbed or emitted when an electron jumps from one energy level to another.
He suggested that electrons must be orbiting the nucleus in a certain fixed energy level or shells He also thought that each electron has it's own level of energy, and rotates the Nucleus -- Jopika
Niels Bohr proposed the electron orbit model in 1913 as an improvement to the previous model proposed by Ernest Rutherford. Bohr's model suggested that electrons orbit the nucleus in specific energy levels, which helped explain the stability of the atom.
The Bohr model describes atoms as having a nucleus surrounded by electrons in fixed energy levels. For neon, which has 10 electrons, the Bohr model would show two electrons in the first energy level, and eight electrons in the second energy level. The electrons in the outermost energy level determine neon's chemical properties.
The Bohr model of the atom suggests that electrons orbit the nucleus in fixed energy levels or shells. For francium, which has 87 electrons, the electrons would be arranged in energy levels around the nucleus based on the Bohr model's principles, with the outermost electron in the highest energy level.
