In quantum mechanics, an atomic orbital (/ˈɔːrbɪtəl/) is a function describing the location and wave-like behavior of an electron in an atom. This function
presence of electrons in other orbitals. If that were the case, the 3d-orbital would have the same energy as the 3p-orbital, as it does in hydrogen, yet
direction of Earth's rotation. An object in such an orbit has an orbitalperiod equal to Earth's rotational period, one sidereal day, and so to ground observers
