Question 544: Atoms & Nuclei

Question

Let R1 be the radius of the second stationary orbit and R2 be the radius of the fourth stationary orbit of an electron in Bohr's model. The ratio $${{{R_1}} \over {{R_2}}}$$ is :

Accepted Answer

Radius of Bohr's orbit depends on principal quantum number (n) as
$$R \propto {n^2}$$
Now, $${{{R_1}} \over {{R_2}}} = {{{{(2)}^2}} \over {{{(4)}^2}}} = {1 \over 4} = 0.25$$
