Bohr's experiment to the atomic model
WebKey Concepts and Summary. Bohr incorporated Planck’s and Einstein’s quantization ideas into a model of the hydrogen atom that resolved the paradox of atom stability and discrete spectra. The Bohr model of the hydrogen atom explains the connection between the quantization of photons and the quantized emission from atoms. WebAug 12, 2024 · Radioactive Atom Activity. In 1913, Ernest Rutherford tested the accepted model of the atom, and found that the atom was different than everyone had previously thought. Using classroom materials, students can simulate the setup of Rutherford’s experiment and recreate his experiment. This activity is intended for middle and high …
