In the early 20th century, experiments by Ernest Rutherford established that atoms consisted of a diffuse cloud of negatively charged electrons surrounding a small, dense, positively charged nucleus. Given this experimental data, Rutherford naturally considered a planetary model of the atom, the Rutherford model of 1911. This had electrons orbiting a solar nucleus, but involved a techn… Web0 is the Bohr radius. The electron Compton wave length is about 1/137 times the size of the atom.

"WebVideo transcript. - In the Bohr model of the hydrogen atom we have one proton in the nucleus. So I draw in a positive charge here and a negatively charged electron orbiting the nucleus, so kind of like the planets orbiting the sun. Even though the Bohr model is not reality it is useful for a concept of the atom. " - In bohr model of hydrogen atom the electron

WebFinal answer. Transcribed image text: Consider a Bohr-model hydrogen atom with electron in the n = 1 orbital. Suppose the atom absorbs a photon. The atom is excited to the n = 2 orbital and then relaxes back down to n = 1 orbital, emitting a photon. The photon is incident on a metal plate and a photoelectron is observed to be ejected.

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.

WebBohr described the hydrogen atom in terms of an electron moving in a circular orbit about a nucleus. He postulated that the electron was restricted to certain orbits characterized by discrete energies. Transitions between these allowed orbits result in the absorption or emission of photons.
