the space which can be occupied by electrons with the same energy level, energy sublevel, and spacial orientation. (see atomic orbital, molecular orbital)

a component of a subshell occupied by up to 2 electrons.

Orbital is the area in space about an atom or molecule in which the probability of finding an electron is greatest. The possible atomic orbitals correspond to subshells of the atom. Thus there is one -orbital for each shell (orbital quantum number = 0). There are three -orbitals (corresponding to the three values of ) and five -orbitals. The shapes of orbitals depend on the value of .

An orbital is a mathematical expression of a 3D geometry where the electron is most likely to be found.

A region of space in an atom occupied by one or two electrons.

orbis, circle, disk] In the current model of atomic structure, the volume of space surrounding the atomic nucleus in which an electron will be found 90 percent of the time.

A mathematically defined region of electron density around one or more atoms.

a mathematical function called a wave function that describes an electron in an atom

an equilibrium state of an electron's wavefunction

a one-electron wave function

a region in space where an electron is most likely to be found

a three-dimensional region around the nucleus where there is a high probability of finding an electron

Usually an eigenfunction of a one-electron hamiltonian, e.g., from Hartree-Fock theory. A spin orbital has an explicit spin and a spatial orbital does not. Orbitals are probably the most useful concept from quantum chemistry: one can think of an atom or molecule as having a set of orbitals that are filled with electrons (occupied) or vacant (unoccupied or "virtual").

A mathematical description of the behaviour of an electron(s) in an atom or molecule. The orbital describes the probable location of the electron, and can be used to calculate other properties such as its energy.

A region of space where there is a high probability of finding an electron in an atom or ion.

The region in space around the nucleus of an atom in which the electrons are most likely to be found.

Representation of electron cloud. See "atomic" and "molecular" orbital.

a representation of the space occupied by an eletron in an atom; the probability distribution for the electron.

a region of space within an atom where an electron in a given subshell can be found

A pattern of probabilities regarding the position of an electron for anatom in a particular energy state. The higher the principal energy level, the more complex the pattern of orbitals.

wavefunction that describes what an electron with a given energy is doing inside an atom or molecule.

( ORH-BIHT-TAHL ) THE CIRCULAR PATH OF AN ELECTRON AROUND THE NUCLEUS,OF THE ATOM, THAT IT REVOLVES AROUND, IS CALLED ITS, ORBIT & ALSO ITS ORBITAL PHENYL ARENE = ( FEH - NIHL AH - REIN ) A MULTI-ARENE RING MOLECULE, WHICH HAS ALL ITS ARENE RINGS, ONE BEHIND THE OTHER AND WHICH ARE SEPARATED BY CH2 METHYLENES

a piercing where the ring passes twice through the ear or other pierced body.

In Iain M. Banks' fictional Culture universe, an orbital (sometimes also simply called an O or a small ring) is a purpose-built space habitat forming a massive ring (though much smaller than a ringworld) rotating to simulate gravity. Its inhabitants, often numbering many billions, live on the inside of the ring, where the continent-sized 'plates' have been shaped to provide all sorts of natural environments and climates.

(L. orbis, circle). Pertaining to the orbit. The use of the word for the socket of the eye first appeared in a translation of the Canon of Avicenna by Gerard of Cremona.

Relating to the eye-socket.

Taking place in orbit, as orbital refueling , orbital launch , or pertaining to an orbit as orbital plane.

In association with the area of the head which contains the eyes.
