Using a quick and easy formula, you can calculate the Bohr model equation to find the frequency of the photons emitted or absorbed by an atom during an electronic transition. In physics the Bohr Model, still commonly used and taught today because of its simplicity, depicts the atom as a small positively charged nucleus with electrons in orbit at different levels, similar in structure to the solar system. It does not explain the Zeeman Effect. He performed a famous experiment whereby atomic particles were passed through gold foil to measure their mass and size. Thus, Rutherford had laid out a basic concept of atom nucleus, whereas Bohr had taken it a step further.

At the beginning of the XX century, Rutherford and colleagues performed a simple experiment that proved the existence of atomic nuclei: small positively charged groups of particles (protons). On a human scale, matter is as solid as something can be. Although this model perfectly fits the atomic structure of hydrogen atom, there were certain limitations when applying this model to other elements. Mathematics is a complex subject.
