## Sample Question

A hydrogen atom's electron transitions from the ground state (n=1) to the first excited state (n=2). Which statement correctly compares the electron's orbital speed in the n=2 state to its speed in the n=1 state?

- (A) The speed in the n=2 state is one-half the speed in the n=1 state.
- (B) The speed in the n=2 state is one-fourth the speed in the n=1 state.
- (C) The speed in the n=2 state is two times the speed in the n=1 state.
- (D) The speed in the n=2 state is four times the speed in the n=1 state.

**Answer: (A)** Comparing orbital speeds requires applying the Bohr quantization condition L=mvr=nℏ and the radius relationship r∝n². Substituting r∝n² into v∝1/r yields v∝1/n, meaning the speed at n=2 is half the speed at n=1.
