/"An atomic orbital is a mathematical function that describes the wave behavior of an electron or pair of electrons in an atom.[1] This function can be used to calculate the probability of finding any electron d 'an atom in any atom. specific region around the nucleus of the atom. The term, atomic orbital, can also refer to the physical region or space where the electron can be calculated to be. present, as defined by the particular mathematical form of the orbital.
Each orbital of an atom is characterized by a unique set of values of the three quantum numbers n, ℓ and m, which correspond respectively to the energy, the angular momentum and a vector component of the angular momentum of the electron (the number magnetic quantum). Any orbital can be occupied by a maximum of two electrons, each with its own spin quantum number s. The simple names s orbital, p orbital, d orbital and f orbital refer to orbitals with angular momentum quantum number ℓ 0, 1, 2 and 3 respectively. These names, along with the value of n, are used to describe the electronic configurations of atoms. They are derived from the description by early spectroscopists of certain series of alkali metal spectroscopic lines as sharp, principal, diffuse, and fundamental. …
Atomic orbitals are the building blocks of the atomic orbital model (also known as the electron cloud model or wave mechanics), a modern framework for visualizing the submicroscopic behavior of electrons in matter. In this model, the electron cloud of a multielectron atom can be considered to be constructed (as an approximation) in an electronic configuration that is a product of simpler hydrogen-like atomic orbitals. The repeating periodicity of blocks of 2, 6, 10 and 14 elements in sections of the periodic table arises naturally from the total number of electrons that occupy a complete set of atomic orbitals s, p, d and f, respectively, although for higher values of the quantum number n, particularly when the atom in question carries a positive charge, the energies of certain subshells become very similar and hence the order in which they are said to be populated with electrons (e.g. Cr [Ar]4s13d5 and Cr2 [Ar]3d4) can only be rationalized somewhat arbitrarily./"
