Question

Quizplus · Accepted Answer

An orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can predict the probability of finding an electron in a specific region around the nucleus, and the volume where an electron is found 90% of the time is indeed referred to as its orbital.
