(anatomy) Obsolete form of orbit.

plural of orbita

(quantum mechanics, chemistry) A mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus.

(quantum mechanics, chemistry) The quantum mechanical behaviour of an electron in a molecule describing the probability of the electron's particular position and energy; approximated by a linear combination of atomic orbitals.

Of or relating to, or forming an orbit (such as the orbit of a moon, planet, or spacecraft). / (anatomy) Of or relating to the eye socket (eyehole).

(chiefly UK) Ellipsis of orbital motorway..

(physics, chemistry) The properties of an atomic orbital or molecular orbital that characterize its symmetry; especially those properties that are conserved in a chemical reaction.

the bony ridge beneath the eyebrow; the browbone

(physics) An orbital formed by the combination of multiple atomic orbitals on the same atom

(chemistry, physics) an atomic or molecular orbital whose energy increases as its constituent atoms are brought closer together - thus generating a repulsive force that hinders bonding
