Quizplus · Accepted Answer

Atomic orbitals describe regions of high electron density (I) and where an electron is likely to be found (II). They are mathematical functions (wave functions) resulting from specific values assigned to quantum numbers in wave equations (III). The description of orbitals as spherical regions (IV) applies specifically to s orbitals, not all orbitals, so it's not universally correct for this statement.

An Atomic Orbital: I.describes a Region of High Electron Density
