   Q1. The radius of the first Bohr orbit is 0.053 nm. What is the radius of the third Bohr orbit?

   • A) 0.159 nm
   • B) 0.477 nm
   • C) 0.053 nm
   • D) 0.0177 nm

   Answer: 0.477 nm

   Explanation: Radius is proportional to n^2; for n = 3, radius = 9 * 0.053 = 0.477 nm; option A is for n = 2.
