Solve problems and use available evidence to discuss the merits and limitations of the Bohr model of the atom
- Bohr model of atom:
- Only particular radii are permitted
- Moving electrons do not lose energy
- The single emission line for hydrogen could be composed of two or more closely spaced lines
- The lines of hydrogen could be split further apart in a magnetic field
- These lines had different intensities
- Merit of Bohr model
- Provides a picture of atomic structure that illustrates some properties of atoms
Example: Bohr orbit is used to explain several properties in relation to magnetism
- Limitations of Bohr model
- Cannot be used to predict structure and measure relative intensities of spectral lines
- Does not apply to multi-electrons atoms
- Provides wrong information about the value of angular momentum of an electron in atom
- Does not follow the Heisenberg uncertainty principle.
