State bohr's postulate of hydrogen atom
WebBohr model of the hydrogen atom was the first atomic model to successfully explain the radiation spectra of atomic hydrogen. Niels Bohr introduced the atomic Hydrogen model in the year 1913. Bohr’s Model of … WebFormulas of Bohr’s postulates. To determine the relationship between the number of the orbit and electrons’ angular moment, the following Bohr model formula is used: mvr = nh/2𝜋. where m is the mass of an electron, v is the velocity, r is the radius of the orbit, h is Planck’s constant, and n is the number of the orbit.
