When discussing the structure of an atom, two of the most commonly discussed models are the Bohr model and the Schrödinger model. In this blog post, we will discuss the key differences between these two models and the implications each has on our understanding of the atom.
Overview of bohr model
The Bohr model of the atom is a simple and intuitive model developed by Niels Bohr in the early 20th century. It explains the behavior of atoms through the concept of electrons traveling in a fixed set of orbits around the nucleus. In contrast, the Schrödinger model of the atom is a more complex, quantum mechanical approach that explains the behavior of atoms through the use of mathematical equations.
While the Bohr model is a useful tool for understanding basic atomic behavior, the Schrödinger model is the more accurate model that is used to explain the behavior of atoms in greater detail.
Overview of schrodinger model
The Bohr and Schrödinger models of the atom are two different ways of understanding the structure of an atom. The Bohr model, developed by Niels Bohr in 1913, proposed that electrons orbit the nucleus of an atom in fixed, discrete energy levels. The Schrödinger model, developed by Erwin Schrödinger in 1926, described atoms as probability clouds, where the electrons have a probability of being found in certain areas around the nucleus.
The Schrödinger model, developed by Erwin Schrödinger in 1926, described atoms as probability clouds, where the electrons have a probability of being found in certain areas around the nucleus. The main difference between the two models is thus the way they explain the position of the electrons. While the Bohr model sees them as particles in a fixed orbit, the Schrödinger model views them as a probability cloud.
This means that the exact location of the electrons is uncertain, but their probability of being found in certain areas is known.
Comparison of bohr and schrodinger models
The Bohr and Schrödinger models are two distinct approaches to understanding the behavior of atoms. The Bohr model is an early atomic model developed by Niels Bohr in 1913, which models the atom as a small, positively-charged nucleus surrounded by electrons that travel in circular orbits around the nucleus. By contrast, the Schrödinger model developed by Erwin Schrödinger in 1926, is based on the idea of wave mechanics, which views the electron as a wave-like entity that travels around the nucleus.
The main difference between these two models lies in how they explain the motion of the electrons. The Bohr model suggests that electrons move in discrete, predetermined orbits around the nucleus, while the Schrödinger model suggests that electrons move in a continuous wave-like fashion.
Furthermore, the Schrödinger model also allows for the possibility of electrons occupying more than one orbit at a time, a phenomenon known as electron tunneling.
Advantages and disadvantages of bohr and schrodinger models
The Bohr and Schrodinger models are two of the most important models in quantum mechanics. Both of these models provide insights into the behavior of atoms and their interactions with other particles.
The Bohr model is a classical approach which uses a fixed set of energy levels to describe the motion of electrons around the nucleus. The Schrodinger model, on the other hand, is a wave-like approach which uses the wave equation to describe the behavior of electrons in atoms. The major difference between these two models is in the way they describe the behavior of electrons.
The Bohr model assumes that electrons move in fixed orbits around the nucleus, while the Schrodinger model views the electrons as a wave, spread out over an area. The Bohr model is more intuitive and easier to understand, while the Schrodinger model is more precise in its description of the behavior of electrons. Another difference between the two models is in how they explain the behavior of particles at high energies.
The Bohr model fails to explain the behavior of particles at high energies, while the Schrodinger model is able to accurately describe this behavior. This makes the Schrodinger model the preferred choice for many applications.
In summary, the Bohr and Schrodinger models are two of the most important models in quantum mechanics. The Bohr model is more intuitive and easier to understand, while the Schrodinger model is more precise in its description of the behavior of electrons. The Schrodinger model is also more accurate when it comes to describing the behavior of particles at high energies.

The Bohr and Schrodinger models of the atom are two of the most important theories in physics. They both attempt to explain the structure and behavior of atoms, but they do so in very different ways.
The Bohr model, proposed by Danish physicist Niels Bohr in 1913, is a classical model that views atoms as having a central nucleus surrounded by electrons orbiting in discrete energy levels. The Schrodinger model, developed by Austrian physicist Erwin Schrodinger in 1926, is a quantum mechanical model that describes atoms as having electrons distributed in a cloud-like region around the nucleus. The Bohr model is based on classical mechanics and considers electrons to be particles, while the Schrodinger model is based on wave mechanics and suggests that electrons are waves.
In addition, the Bohr model offers a simple, intuitive explanation of the atomic structure, while the Schrodinger model provides a more precise, mathematical approach.
Conclusion
In conclusion, the Bohr model and the Schrodinger model are two very different atomic models used in chemistry. The Bohr model is a classical model that explains the behavior of electrons in an atom, while the Schrodinger model is a quantum mechanical model that explains the behavior of electrons in an atom.
Both models have been used to explain the behavior of electrons in atoms, but the Schrodinger model is more accurate and is used more often in modern chemistry.
