Quantum Mechanical Model: A model that uses complex shapes of orbitals (regions around the nucleus where an electron is likely to be found), volumes of space in which there are likely to be electrons.

Energy Levels:

The specific energies an electron in an atom can have.

Orbitals:

Regions within an atom where electrons are most likely to be found.
