  1. The quantum mechanical model of the atom - Khan Academy

    This model, which is the basis of the modern understanding of the atom, is known as the quantum mechanical or wave mechanical model. The fact that there are only certain allowable states or …

  3. Atomic models and periodicity | High school chemistry | Khan Academy

    Explore modern theories that describe atomic structure through various models, such as the Bohr model and the quantum mechanical model. Learn about the benefits and limitations of each model and …

  4. Quantum numbers (video) | Khan Academy

    The Bohr model turns out to be incorrect, and quantum mechanics has proven to be the best way to explain electrons in orbitals. We can describe those electrons in orbitals using the four quantum …

  5. The Bohr model (article) | Khan Academy

    The nucleus is shown as a tiny clump of red protons and purple neutrons in the center of the atom. Another name for the electron cloud model is the quantum mechanical model. It was first developed …

  6. Introduction to electron configurations (video) | Khan Academy

    The x,y,z symbols identifying each orbital correspond to their magnetic quantum number which tells us the specific orbital it is. These are mathematical functions which generally tell you which axis (in a 3D …

  7. Bohr's model of hydrogen (article) | Atoms | Khan Academy

    The modern quantum mechanical model may sound like a huge leap from the Bohr model, but the key idea is the same: classical physics is not sufficient to explain all phenomena on an atomic level.
