Bohr Model of Hydrogen Atom
In 1913 Neils Bohr built on the work of Max Planck and Albert Einstein and proposed that the movement of electrons within an atom was quantized. Bohrs Model is an atomic model proposed by a Danish Physicist Niels Bohr in 1913.

As a hydrogen atom consists of one electron and a proton in which the mass of an electron is negligible therefore it can be said that the mass of a proton is equal to a hydrogen.
. Developments Leading to Bohrs Model of Atom. A hydrogen-like atom or hydrogenic atom is any atom or ion with a single valence electronThese atoms are isoelectronic with hydrogenExamples of hydrogen-like atoms include but are not limited to hydrogen itself all alkali metals such as Rb and Cs singly ionized alkaline earth metals such as Ca and Sr and other ions such as He Li 2 and Be 3 and isotopes. In 1913 Niels Bohr obtained the energy levels and spectral frequencies of the hydrogen atom after making a number of simple assumptions in order to correct the failed classical model.
In other words Bohrs work sug. The Bohr model of the atom a radical departure from earlier classical descriptions was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models. According to this model In an atom.
The Bohr model and all of its successors describe the. So here I just wanted to show you that the emission spectrum of hydrogen can be explained using the Balmer Rydberg equation which we derived using the Bohr model of the hydrogen atom. The electron in Bohrs Hydrogen atom revolves around the nucleus with a speed of 218 10 6 ms in orbit of radius 53 10-11 m.
Electrons can only be in certain discrete circular orbits or stationary states thereby having a discrete set of possible radii and energies. Composition of an Atom. Bohr model description of the structure of atoms especially that of hydrogen proposed 1913 by the Danish physicist Niels Bohr.
Inside each shell there may be subshells corresponding to different rates of rotation and. Bohrs Model of the Hydrogen Atom. All of the orbitals that have the same value of n make up a shell.
In the quantum mechanical version of the Bohr atomic model each of the allowed electron orbits is assigned a quantum number n that runs from 1 for the orbit closest to the nucleus to infinity for orbits very far from the nucleus. So even thought the Bohr model of the hydrogen atom is not reality it does allow us to figure some things out and to realize that energy is quantized. Hydrogen Bohr model was based on some assumptions which are listed below.
The singular proton of the hydrogen atom or the protons and neutrons of the hydrogen-like speciesex- He Li 2 etc are present in the centre of the atom in a positively charged nucleus.
