Bohr’s theory was an important stage in the development of quantum concepts of the structure of the atom. Bohr determined the radius of the hydrogen atom and the energies of the stationary states of the atom. This made it possible to calculate the frequencies of electromagnetic waves emitted and absorbed by the hydrogen atom. Bohr’s theory makes it possible to describe not only the hydrogen atom, but also the hydrogen-like ions of other elements.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
