1Then it shud be like this
a = na/100
So n= 100
Hence the ans
If the atom Fm257100 follows the Bohr Model & the radius of Fm257100 is n times the Bohr radius , then find n :
(A) 100
(B) 200
(C) 4
(D) 1/4

19rn = bohr radius /z (z=atomic number)
let bohr radius =a
=> na =a/100
=> n=1/100
.....but the answer is not matching with the given ones !
19the question says this : the radius of the atom in n times the bohr radius !
19what ? whats this ? what is the logic ?
i say , a=bohr radius =>na= radius of the given atom !
also radius of an atom of atomic no Z= a /z = a/100
19what you have done is bohr radius = n times the radius of the given atom !
106yeah you are correct
but the question is a bit vague, it should have given Fm99+
