The Bohr radius (a
0
or r
Bohr
) is a physical constant, approximately equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state. It is named after Neils Bohr, due to its role in the Bohr model of an atom. Its value is 5.2917721067(12)×10−11 m
Bohr radius for nth orbits,
r_n = .529 n^2/z; its applicable only for H,He+,Li+2
Where ,
n is no. of orbits, n=1,2,3…………
z is atomic no.of hydrogen which is equal to 1.
A/c to question,
We have required for finding Bohr radius in 2nd orbit, we have z=1, n=2.
So that ,
r_n = .529 n^2/z = .529 × 2^2/1 = .529 × 4 = 2.116 ans__
