What happened to Bohr's model of atom in the light of uncertainty principle ? Explain the concept of 'probability'. Define 'atomic orbital'.

Solution

Bohr's model of the atom assumes fixed orbits and trajectories for the electron. Simultaneously known orbits and trajectories violate the Heisenberg Uncertainty Principle. The problem is, electrons do not travel in fixed orbits, and they do not travel with fixed trajectories.

Atomic orbitals are the quantum states of the individual electrons in the electron cloud around a single atom. Specifically, atomic orbitals are the quantum states of the individual electrons in the electron cloud around a single atom.



The characteristics of each atomic orbital are dependent upon the values of the following quantum numbers :

The principal quantum number (denoted by the symbol ‘n’)
The azimuthal quantum number, also known as the orbital angular momentum quantum number (denoted by the symbol ‘l’)
The magnetic quantum number (denoted by the symbol ‘m’)
