Study Notes

Quantum Mechanical Model

The Bohr model is a basic model that describes electrons occupying specific energy levels at fixed distances from the nucleus.
The Bohr model is insufficient for atoms with more than one electron.
A more accurate model is the quantum mechanical model which uses probability to describe the location of electrons.
The quantum mechanical model describes the probability of finding an electron in specific locations within the atom rather than defining precise orbits.
