	General Chemistry Online: FAQ: Electrons in atoms: What are the shapes and designations of the f orbitals?
		The exotic, complex f orbital shapes are rarely shown in textbooks.
		Even for elements beyond cerium, the f orbitals are deeply buried beneath the valence shell and they rarely play an important role in chemical change or bonding.

		The orbital floor is separated from the lateral wall by the inferior orbital fissure, no sharp line of demarcation from medial wall.
		Orbital exenteration is indicated with a persistently recurring benign lesion that threatens to invade cranial cavity or when lesion threatens to attain unresectability or cause blindness.
		The posterior 15mm of the lateral orbital wall encompasses the superior fissure and cannot be removed with a lateral orbitotomy.

		Specifically, atomic orbitals are the quantum states of the individual electrons in the electron cloud around a single atom.
		The atomic orbital concept is therefore a key concept for visualizing the excitation process associated to a given transition.
		Orbitals with the same value of n and also the same value of l are even more closely related, and are said to comprise a "subshell".

	H atom orbitals in 3D
		The various pictures of H atom orbitals in the text or elsewhere on our web site are important places to turn to learn how atomic orbital quantum numbers control the size, shape, orientation, and nodal patterns of orbitals in general.
		For the f orbital, two of the three nodal planes are cones, but the third is a flat plane, the xy plane again.
		The sphere represents the orbital (which is, of course, spherically symmetric), and its color is a shade of green with an intensity proportional to the value of the radial probability funtion at each animation radius.

	Concepts of Orbital Reconstruction
		The canthal attachments are extremely strong and are composite structures in which extensions of the fibrous tarsus, the orbital septum, the lateral horns of the aponeurosis of the levator palpebrae superioris and, in the medial canthus, the tendons of the various heads of the orbicularis muscle all share.
		The inferior orbital fissure is approximately 2cm long and is a bony defect between the orbital floor and the lateral wall in the posterior orbit.
		The precise location of the ocular globe in three dimensions is determined by several factors: the relative volume of the orbital cavity and that of its soft tissue contents, the configuration of the walls of the orbit, and the orientation and insertion of tendon attachments to the bony rim.

		The orbitals are not all shown on the same scale (except for the 1s and 2s orbitals, which are on the same scale).
		In this orbital most of the electron "density" is in the two outer lobes of the orbital, but there is some electron density in the two small inner lobes.
		The 2p-sigma orbital is a bonding orbital which can be approximated by two 2p orbitals with their electron density lobes pointing toward each other.

	The Actinide Research Quarterly: 1st Quarter 2004 (Site not responding. Last check: )
		The type of orbital (s, p, d, or f) that the valence electrons reside in is a function of the elements' position in the periodic table.
		Thus, electrons in the 3s orbital of sodium (Na) are higher in energy and farther away from the nucleus than electrons found in the 2s orbital of lithium (Li).
		In contrast to the transition elements, the seven f orbitals, which are found in lanthanides and actinides, are less well understood.

	Atomic Orbitals
		The orbital and atomic images included are rigorously calculated using the Schrödinger equation (they are all based on hydrogen, so only two particles are involved, the proton and one electron - we assume other atoms are similar).
		Sample orbitals for n = 1-6 are provided to demonstrate size relationships and the increasing complexity of orbitals as n increases.
		Orbitals in the rest of the Periodic Table are related to these hydrogenic orbitals.

		The 2s atomic orbital on F is so much lower in energy than the valence 1s atomic orbital on hydrogen that no molecular orbital will form between them.
		Finally, the 2p(F) atomic orbitals -- which are each perpendicular to the one previously used to construct the bonding and antibonding molecular orbitals -- do not give net interference combinations with the 1s(H) and so remain unchanged in the HF molecule.
		The lowest molecular orbital is virtually indistinguishable from the 2s atomic orbital on F (because of the large energy difference with H's atomic orbital).

		It enters the orbit through the superior orbital fissure, above the ophthalmic vein, from which it is separated by a lamina of dura mater.
		As these nerves pass forward to the superior orbital fissure, the oculomotor and ophthalmic divide into branches, and the abducent nerve approaches the others; so that their relative positions are considerably changed.
		In the orbit, the trochlear, frontal, and lacrimal nerves lie immediately beneath the periosteum, the trochlear nerve resting on the Obliquus superior, the frontal on the Levator palpebræ superioris, and the lacrimal on the Rectus lateralis.

	Atomic Orbitals
		Electrons are added to the various orbitals, filling the higher energy levels as the size of the atom increases.
		The various shapes that correspond to the values of l are referred to as s, p, d and f orbitals.
		The first quantum number determines the size, i.e., a 1s orbital is smaller than a 2s orbital which is smaller than a 3s orbital, etc. The energy of an orbital is determined mostly by the first two quantum numbers.

	Spartanburg SC \| GoUpstate.com \| Spartanburg Herald-Journal
		The Azimuthal quantum number (or orbital angular momentum quantum number) symbolized as l (lower-case L) is a quantum number for an atomic orbital which determines its orbital angular momentum.
		The azimuthal quantum number is the second of a set of quantum numbers (the principal quantum number, following Spectroscopic notation, the azimuthal quantum number, the magnetic quantum number, and the spin quantum number) which describe the unique quantum state of an electron and is designated by the letter l.
		Orbitals with higher l than given in the table are perfectly permissible, but these values cover all atoms so far discovered.

	Quantum number Summary
		So for any orbital there can be many shapes associated with a particular size depending upon what the principle quantum number is. The first five shapes associated with the orbital quantum numbers are referred to as s, p, d, and f.
		There are five possible orientations for d orbitals because of the range of possible magnetic quantum numbers associated with this orbital and there are seven possible orientations for f orbitals described by the magnetic quantum numbers.
		Note that molecular orbitals require totally different quantum numbers, because the Hamiltonian and its symmetries are quite different.

		The orbital shape quantum number has the following values and designations for the shape of the probability region in which the electrons are most probably to be found.
		f - orbitals - these are more difficult to describe in a graphical sense, but it turns out there are 7 possible f -orbitals, each being able to contain 2 electrons, for a maximum total of 14 electrons.
		But, beginning with n = 4, there is overlap between the energies of s and d orbitals, and thus the 4s orbital is filled before the 3d orbitals, and the 4p orbitals do not contain electrons until the 3d orbitals are filled.

	Learning Quantum Mechanics
		A (s) orbital can be represented by shaping the wire into a circle, if you can imagine the electron is following the circular path of the wire, then spin the wire so now the electron is moving not only in a circle but the circle is also spinning to create a spherical shape.
		A (p) orbital can be represented by shaping the wire into a dumbbell shape, and grabbing the long ends of the dumbbell shape with both hands and twist or turn it between your fingers.
		A (f) orbital is made by shaping the wire into two (d) orbital shapes.

	Resonant orbital evolution in the putative planetary system of PSR1257 + 12
		have proposed that the planetary explanation is amenable to a simple test: the deduced parameters put the planets near an orbital resonance, in which case secular evolution of the orbits should be observable in a matter of years.
		Detection of such orbital evolution would yield the masses and orbital inclinations of the planets.
		The character of the predicted orbital parameter perturbations is then markedly different from the periodic perturbations that result from only a near-resonance.

		The first number is the shell number, the s, p, d, or f represents the type of subshell, and the last number shows the number of electrons in the subshell.
		The filling of a d subshell is represented by the transition elements (ten elements), and the filling of an f subshell is shown in the lanthanide and actinide series (fourteen elements).
		The shape of the d and f subshells is very complex with a spatial distribution.It can only be visualized in 3-D. Electron configuration is the "shape" of any electron around an atom.

	Two Different Extensions For The Periodic Table
		By comparison, the f orbital, in seeking to satisfy the same tendency in similar occasions, chooses to receive this required electron from the d orbital, its closest in energy level within the same period (as in the electron configurations of Eu, Yb, Am, No, Uqp, Upb).
		Should the g orbital, in seeking the same, receive this 'occasional electron' from d again (as is the case with f) or should it receive it from, its closest, the f?
		Thus, if g behaves in a similar fashion as f and needs (in certain instances or occasions) to get its electron from d, we have no problem with that because d already has one electron available to donate as is shown in the extended periodic table suggested by Glenn T. Seaborg.
