SUMMARY

The Niels Bohr model cannot be applied to elements beyond hydrogen due to its oversimplification of atomic structure. While it provides basic insights into quantum mechanics, it fails to account for the complexities of electron orbitals and the Pauli exclusion principle. Full quantum mechanics is necessary to accurately describe the behavior of electrons in multi-electron atoms, which is essential for understanding chemical properties and interactions.

PREREQUISITES
  • Understanding of the Bohr model of the atom
  • Basic knowledge of quantum mechanics
  • Familiarity with atomic orbitals
  • Knowledge of the Pauli exclusion principle
NEXT STEPS
  • Study the Schrödinger equation and its application in quantum mechanics
  • Explore the concept of atomic orbitals in detail
  • Learn about the Pauli exclusion principle and its implications in chemistry
  • Investigate advanced quantum mechanics topics, such as electron correlation and many-body systems
USEFUL FOR

Students of physics, chemists, and educators seeking to deepen their understanding of atomic structure and quantum mechanics.

Hi,
we know that we can find the radius and energy of the orbits of hydrogen.now why is it so that we cannot apply the same formulas for other elements by using the equations given by bohr.if there are complications what are they?

Main complication is that the Bohr model is rather far from reality even if it illustrates very simply the fundamentals of quantum mechanics.

However, for most of atomic physics the full quantum mechanics is needed.

For example, orbitals describe stationary waves of electrons in the atom in a very precise way. This description is much more elaborated than the Bohr model. Without, you could never explain chemistry.

As another example you should think to the Pauli exclusion principle: no more than two electron can manage to eccupy the same orbital if they have oppiste spins. Again this is not included in the Bohr model.
