An orbital: I) describes a region of high electron density.
II) describes a region in an atom where an electron is likely to be found.
III) is a wave function resulting from specific values assigned to quantum numbers in wave equations.
IV) describes a spherical region around a nucleus where an electron can be found.

Question

Quizplus · Accepted Answer

An orbital is a wave function (III) that describes a region in an atom where an electron is likely to be found (II), and it represents a region of high electron density (I). However, not all orbitals are spherical, so IV is incorrect.
