The emission spectrum of hydrogen shows discrete, bright, colored lines. Which characteristic of the Bohr model is best supported by this observation?
Energy is released when an electron moves to a higher energy level.
Smaller atoms have fewer spectral lines than larger atoms.
The energy of an electron increases with distance from the nucleus.

Electrons cannot exist in locations other than in specific orbits.
Reason: The discrete bright lines show photons emitted only at specific energies — exactly the differences between allowed energy levels. That supports Bohr's idea of quantized electron orbits. (Option 1 is wrong — energy is released when an electron drops to a lower level, not when it moves to a higher.)
