What is the difference between Schrodinger and Bohr?

In the Bohr Model, the electron is treated as a particle in fixed orbits around the nucleus. Schrodinger’s model (Quantum Mechanical Model) allowed the electron to occupy three-dimensional space. It therefore required three coordinates, or three quantum numbers, to describe the distribution of electrons in the atom.

What are the two major distinctions between Bohr and Schrodinger’s model?

As with the Bohr model the energies of electrons are quantized, or have only certain allowable values. Schrodinger’s equations are based on four quantum numbers. This changes the Bohr model to one that is three dimensional and has energy sub-levels (s,p,d,f) for each principal quantum number.

Is Schrodinger’s wave equation similar to Bohr’s theory?

Total energy is the same in Bohr-Sommerfeld and Schrodinger hydrogens. Comparing the energies of Bohr model and Schrodinger equation, they are just consistent with each other. And the principal quantum number “n” is the sum of radial and angular ( wave ) numbers in both models.

What is the difference between the Bohr and quantum model?

The Bohr model and quantum model are models that explain the structure of an atom. The key difference between Bohr and quantum model is that Bohr model states that electrons behave as particles whereas quantum model explains that the electron has both particle and wave behavior.

What is the difference in the Bohr’s model and quantum mechanical model about finding the location of the electron?

Unlike the Bohr model, the quantum mechanical model does not define the exact path of an electron, but rather, predicts the odds of the location of the electron. This model can be portrayed as a nucleus surrounded by an electron cloud.

Which of the following is known as the Schrödinger equation?

The Schrödinger equation is the fundamental equation of physics for describing quantum mechanical behavior. It is also often called the Schrödinger wave equation, and is a partial differential equation that describes how the wavefunction of a physical system evolves over time.

How does the orbital angular momentum differ between the Bohr model and the quantum mechanical calculation?

There is always a radial wave function in place of the radius of the orbit as suggested by Bohr. In quantum mechanics, the angular momentum is also quantized but not in the same way as the Bohr model. Since the uncertainty principle does not allow this but Bohr model gives the angular momentum exactly.

Is Schrödinger equation wrong?

In actual atoms, interelectronic Coulomb energy changes “dependent” on other Coulomb terms (= electron-nucleus ) and atomic kinds. This is the reason why Schrodinger equation is wrong, and cannot solve multi-electron atoms.
