What is the equation or formula for Bohr model for second postulate ?

Posted in Atoms, Molecules and Nuclei | Email This Post Email This Post |

Electron of an atom orbiting around a nucleus are permitted to revolve in those orbit for which angular momentum is equal to integral multiple of h/2π, where h is the Planck’s constant.

The equation or formula for Bohr model for postulate 2 is given as,

m vn rn = n h / 2π

m= mass of an electron (9.1 x 10–31 Kg)

vn = velocity of electron in nth state (orbit)

h= Planck’s constant (6.67 x 10–34 J-s)

rn = radius of nth orbit

n is a positive integer
