I'm trying to follow the book for the introduction to quantum mechanics by Griffiths. Next Post. The Bohr radius (a 0 or r Bohr) is a physical constant, equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state.

I'm following the part where he is solving Schrödinger's equation for the hydrogen atom. It is named after Niels Bohr, due to its role in the Bohr model of an atom. http://musr.physics.ubc.ca/~jess/hr/skept/QM1D/node3.html 2009/05/02 The Bohr Radius Page 2 of 2. for the radius of the Bohr orbit of the H atom.

Printer Friendly Version : By the middle of the 19th century it was well known by chemists that excited hydrogen gas emitted a distinct emission spectrum. Explain Bohr model of hydrogen atom: Bohr’s postulates - Derivation of Bohr radius - Derivation of energy of electron in stationary states of hydrogen atom. Its value is 5.291 772 109 03 (80) × 10 −11 m. atoms; class-12; Share It On Facebook Twitter Email. There, he found the Bohr It was noted that the same lines were always present and that the spacing between these lines became smaller and smaller. It is the first hint that orbitals are based on the strong force – creating a new orbital force .
