Any immobile ship An orbital is generally assumed to be in in orbit around a given planet (thus its immobility and the root of the term orbital) It is also generally assumed to have racks, though this is certainly not a requirement
In the approximation that each electron in a molecule has a distinct, independent °wave function, the spatial distribution of an electron wave function corresponds to a molecular orbital These, in turn, can be approximated as sums of contributions from the orbitals characteristic of the isolated atoms An electron added to a molecule--or, similarly, one excited to a higher-energy state within a molecule--would occupy a state with a different wave function from the rest; an unoccupied state of this kind corresponds to an unoccupied molecular orbital Orbital-symmetry effects on reaction rates arise when a reaction requires °overlap between two lobes of the orbitals on each of two °reagents: if the algebraic signs of the wave functions in the facing lobes do not match, bond formation between those orbitals is prohibited
Orbital describes things relating to the orbit of an object in space. The newly discovered world followed an orbital path unlike that of any other planet. a road that goes around a large city to keep the traffic away from the centre = ring road. adj. Mathematical expression, called a wave function, that describes properties characteristic of no more than two electrons near an atomic nucleus or molecule. An orbital can be considered a three-dimensional region in which there is a 95% probability of finding an electron. Atomic orbitals are designated by a combination of numerals and letters (e.g., 1s, 2p, 3d, 4f). The numerals are the principal quantum number and are related to the atomic energy level and distance from the nucleus; the letters indicate the orbital's angular momentum and hence its shape. An s orbital with zero net orbital angular momentum is spherical. A p orbital with one fundamental unit of angular momentum, , is shaped somewhat like a dumbbell ( is Planck's constant, h, divided by 2). The shapes of the other orbitals are more complicated. Molecular orbitals have geometries determined by the overlap of two or more atomic orbitals and are designated by Greek symbols, e.g., and
Another word for a ring road 'Orbital' tends only to be used for very large or important ring roads - London's industrial-size ring road, the M25, is the original one The term is often applied to the M60 also, and recently Blackburn has started signposting its own slightly less impressive ring road as an orbital too
The region in space around the nucleus where the probability of finding an electron is maximum is known as an orbital of that electron The region of higher probability of electron cloud is called as orbital Orbitals are named by the letters s,p,d and f Each has a typical shape When l = 0, orbital is spherical, designated by letter s When l = 1, orbital is dumb-bell shaped, designated by letter p When l = 2, orbital is four lobed, planar , designated by letter d When l = 3, orbital is complicated in shape, designated by letter f
