Answers below are taken from the article’s stored facts, so they match what the student read.

1. When was Gustav Ludwig Hertz born?July 22, 1887
2. Where was Gustav Ludwig Hertz born?Hamburg, Germany
3. What is Gustav Ludwig Hertz known for?Experimental verification of quantized atomic energy levels through electron-atom collisions (Franck-Hertz experiment)
4. What is the related topics?Quantum mechanics, atomic physics, spectroscopy, gas discharges
5. What is the Franck-Hertz experiment?It was a test where electrons were fired at mercury atoms, showing that atoms only absorb energy in specific amounts.
6. Why did the Franck-Hertz experiment matter?It proved that atoms have discrete energy levels, a key idea of quantum mechanics.

Quantization of Energy: The principle that energy exists in discrete, indivisible units called quanta, rather than in a continuous spectrum.
Ground State: The lowest possible energy level that an electron can occupy within an atom.
Excited State: An energy level of an atom higher than its ground state, occupied by an electron that has absorbed energy.
