Bohr's experiment

WebFeb 24, 2024 · The solar system or planetary model of the atom was attractive to scientists because it was similar to something with which they were already familiar, namely the solar system. Figure 9.4. 3: Niels Bohr with Albert Einstein at Paul Ehrenfest's home in Leiden (December 1925). Unfortunately, there was a serious flaw in the planetary model. WebFigure 7.3.6: Absorption and Emission Spectra. Absorption of light by a hydrogen atom. (a) When a hydrogen atom absorbs a photon of light, an electron is excited to an orbit that has a higher energy and larger value of n. (b) Images of the emission and absorption spectra of hydrogen are shown here.
