The radius of the stationary state which is also called Bohr radius is given by the expression

\mathrm{r_n=n^2 a_0}

where the value of

\mathrm{a}_0

is

View answer and explanation

Correct option: A

52.9 \mathrm{~pm}

Option A (

52.9 \mathrm{~pm}

) is correct because the Bohr radius, denoted as

a_0

, has a value of 52.9 picometers.
