On the basis of Bohr's atomic model, find an expression for the radius of ntl orbit of an atom.

Text Solution

Verified by Experts

An atom consistants fo a charge + ze electron having chare e revoles around the nucleus in circular orbit
and `f=(1)/(4 pi epsilon_(0))(e)/(r^(2))`
According to Bohr .s postulate of angular momentum
`mvr=(nh)/(2pi)`
Put value of v in(i)
`r=4pi epsilon_(0)(pi^(2)h^(2))/(4pi^(2)ze^(2)m)`
which is the requied expression for the radius nth orbit of an atom
