24. Select the evidence that Dalton used to conclude his findings. (a) Used flame tests to determine that electrons become excited with more energy and
then release that energy as atomic spectra.
(b) Performed a series of experiments using pressure, properties of gases, and properties of compounds.
(c) Passed a cathode ray between positively and negatively charged plate.
the cathode ray attracting to the positively charged plate.
(d) Bombarded a thin layer of gold foil with alpha particles and detected that some alpha
particles passed through the gold foil while others deflected.
