· What is the Bohr model of potassium?1500 · The Bohr model shows the atom as a central nucleus containing protons and neutrons with the electrons in circular orbitals at specific distances from the nucleus (Figure 1) These orbits form electron shells or energy levels, which are a waySo in the last video I showed you how to get this equation using a lot of physics and so it's actually not necessary to watch the previous video you can just start with this video if you want and E one we said was the energy associated with an electron and the lowest energy level of hydrogen and we're using the Bohr model and we calculated the value for that energy to be equal to negative

· Bohr's Model of the Atom In 1913, Neil Bohr proposed a theory to explain the stability of an atom, where electrons revolved around the nucleus at certain energy levels Each orbital had a different radius and electrons revolving in a particular orbit did not radiate energy This happened even if the electron had accelerated motion around the nucleus Bohr put forth some postulates that supported his atomFriends We are working hard for more Educational videos for You and Learners Please Subscribe to our channel and click the bell icon If you like this videoToday the atomic model is very similar to Bohr's model The modern atomic model, the Wave model, does not have exact orbits like Bohr did Instead the modern model has a scatter region surrounding the _____ where an _____ will probably, but not certainly, be found The Atomic Model of Matter Key More than 00 thousand years ago, A Greek philosopher namedDemocritus led a
Bohr's model of the atom (ESAAR) There were, however, some problems with Rutherford's model for example it could not explain the very interesting observation that atoms only emit light at certain wavelengths or frequencies Niels Bohr solved this problem by proposing that the electrons could only orbit the nucleus in certain special orbits at different energy levels around the nucleusBohr's Model of the Atom •Focuses on electrons and their arrangement •Bohr stated that electrons move with constant speed in fixed orbits around the nucleus, like planets around a sun •Bohr correctly assigned energy levels to electrons, but electrons do not move in fixed orbits around the nucleus Bohr's Model of the Atom Electron Nucleus Valence Electron Electron Cloud ModelHe hypothesizes that the angular momentum of an electron in orbit around a proton is quantized (ie it can only be a discrete multiple of a certain number) Under this simple assumption he managed to compute the energy of the
