text: I don't know what a suborbital is, but an orbital is the region where an electron spends 90 percent of its time. In other words, it's the region where the electron has a .9 probability of being there. This is based on psi squared from the Schrodinger equation.\n\nAt each energy level, there exists orbitals. These orbitals are defined by a set of quantum numbers: n, l, ml, me
