Bohr Model of Hydrogen Atom Postulates
The Bohr model of the hydrogen atom assumes that the Bohr model of the hydrogen atom has its own unique assumptions, which are related to the atomic structure and electronic behavior. It is also the gist of real physics research.
First, the electron moves around the nucleus in a specific circular orbit. This orbit is non-arbitrary and has a fixed energy, called a stationary orbit. Electrons live in this orbit, do not radiate or absorb energy, and the atom is in a stable state.
Second, the electron transition hypothesis. When an electron absorbs or releases a specific energy, it can jump from one orbit to another. The absorbed energy transitions to a higher energy level, and the released energy falls back to a lower energy level. And the energy change is equal to the energy difference between the two orbitals.
Third, the angular momentum quantization hypothesis. The angular momentum of the electron's movement around the nucleus is quantized, that is, the angular momentum can only take a specific discrete value, which is expressed in the formula: $L = n\ frac {h} {2\ pi} $, where $L $is the angular momentum, $n $is the quantum number, the value is a positive integer, and $h $is the Planck constant.
Therefore, the assumption of the Bohr model has made outstanding achievements in explaining the phenomena such as the spectrum of the hydrogen atom, laying a solid foundation for the development of atomic physics and guiding future generations to explore the mysteries of the microscopic world.
