question 4 (1 point)
bohr believed that electrons can possess only specific amounts of energy, based on what observation?
alpha particles were deflected by an electric field
the continuous spectra was produced by excited atoms
most alpha particles went straight through the gold foil
the line spectra produced by excited atoms
some alpha particles were deflected by the gold foil

Explanation:

Bohr's model of the atom was based on the observation of line spectra. When atoms are excited (e.g., by heat or electricity), they emit light at specific wavelengths (line spectra). This suggests that electrons can only exist in certain energy levels. If electrons could have any energy (as in a continuous spectrum), a continuous range of wavelengths would be emitted. The deflection of alpha particles (options with alpha particles) was related to Rutherford's model (nucleus discovery), not Bohr's energy - level concept.

Answer:

the line spectra produced by excited atoms
