15.2 The Bohr Model of Atomic Structure
Notes
Electrons occupy specific energy levels. They absorb or emit photons when they jump between levels: $E_{photon}=|E_f-E_i|$.
Practice
An electron drops from −3.4 eV to −13.6 eV. The emitted photon's energy:
$13.6-3.4$.
An atom absorbs a photon when:
Quantized energy.
Energy levels in the Bohr model are:
Specific values only.
