Final answer:
An LE model, or atomic orbital model, describes the type of atomic orbitals within an atom and their shapes and directions.
Step-by-step explanation:
An LE model, or atomic orbital model, describes the type of atomic orbitals that exist within an atom. Atomic orbitals are regions in space that enclose a certain percentage of the electron probability and are sometimes referred to as 'clouds' of probability. These atomic orbitals have specific shapes and directions, which are important for chemists when analyzing how atoms are bound together to form molecules.
