According to the bohr's atomic model, the relation between principal quantum number (n) and radius of orbit (r) is

Options

A. `r prop n^(2)`
B. `rprop(1)/(n^(2))`
C. `r prop (1)/(n)`
D. `r prop n`

Answer

D

Explanation

Electron angular momentum about the nucleus is an integral multiple of `(h)/(2pi)`, where h is planck's constant.
thus, `l omega=mvr=(nh)/(2pi)`
hence, `r prop n`
