Bohrs model of hydrogen (article) | Atoms | Khan Academy Bohr's model of the hydrogen atom: quantization of electronic structure Bohr’s model of the hydrogen atom started from the planetary model, but he added one assumption regarding the electrons What if the electronic structure of the atom was quantized?
Learn: The Bohr model (article) | Khan Academy Strengths The Bohr model represents the particle nature of electrons So, it's easy to see that the atom above contains two electrons As we'll discuss later in the article, electrons exist at specific energy levels in atoms The Bohr model represents these energy levels as rings
The quantum mechanical model of the atom - Khan Academy The following diagram of the Bohr model shows the electron existing in a finite number of allowed orbits or shells around the nucleus A diagram of the Bohr model of the hydrogen atom Electrons move in circular orbits that are at fixed distances from the nucleus Light is emitted when excited electrons, n> 1 , relax back to a lower energy level
Atomic spectra (article) | Atomic structure | Khan Academy Observe the Bohr model of hydrogen To begin, select the Bohr model from the list of atomic models on the right Focus your attention on the center square Notice the red proton, the blue electron, and the dashed rings

Bohr model energy levels (video) | Atoms | Khan Academy Calculating electron energy for levels n=1 to 3 Drawing a shell model diagram and an energy diagram for hydrogen, and then using the diagrams to calculate the energy required to excite an electron between different energy levels
Learn: The periodic table, electron shells, and orbitals Electron shells and the Bohr model An early model of the atom was developed in 1913 by the Danish scientist Niels Bohr (1885–1962) The Bohr model shows the atom as a central nucleus containing protons and neutrons, with the electrons in circular electron shells at specific distances from the nucleus, similar to planets orbiting around the sun
