A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. [1] The term seems to have been first used by Charles Janet. [2] Each block is named after its characteristic orbital: s-block, p-block, d-block, f-block and g-block.

Spdf or SPDF may refer to: S/PDIF , a format for communicating digital audio across coaxial or fiber optic cabling. Electron configuration , for which there is an obsolete system of categorizing spectral lines as " s harp", " p rincipal", " d iffuse" and " f undamental"; also the names of the sub shells or orbitals
These blocks appear as the rectangular sections of the periodic table. The single exception is helium , which despite being an s-block atom is conventionally placed with the other noble gasses in the p-block due to its chemical inertness, a consequence of its full outer shell (though there is discussion in the contemporary literature on whether ...
In many cases, multiple configurations are within a small range of energies and the small irregularities that arise in the d- and f-blocks are quite irrelevant chemically. [1] The construction of the periodic table ignores these irregularities and is based on ideal electron configurations. [2]
Here [Ne] refers to the core electrons which are the same as for the element neon (Ne), the last noble gas before phosphorus in the periodic table. The valence electrons (here 3s 2 3p 3 ) are written explicitly for all atoms.
