1. The problem statement, all variables and given/known data Calculate the radius of the n = 6 Bohr orbit in O7+(oxygen with 7 of its 8 electrons removed). A) 190 pm B) 167 pm C) 238 pm D) 214 pm 2. Relevant equations I believe that the relevant equation is r(sub n)=(n^2)*a(sub b) where a(sub b)= Bohr's radius= 5.29*10^-11 m 3. The attempt at a solution I calculated it for what I believed to be n=6, but I got an incorrect answer. The correct answer is (C) 238 pm, but I do not understand why. Any help is greatly appreciated!
