Answer» Answer: block of the periodic table is a set of elements unified by the orbitals their valence electrons or vacancies lie in.[1] The term appears to have been first used by Charles Janet.[2] Each block is named after its characteristic orbital: s-block, p-block, d-block, and f-block. A long periodic table showing, from left to right: the s-, d-, f-, and p-blocks. The f-block, normally SHOWN as a footnote, here SPLITS the d-block into two. While this splitting is the more common form in the literature, a minority advocates placing the f-block between the s- and d-blocks.[1] The block names (s, p, d, and f) are derived from the spectroscopic notation for the value of an ELECTRON's azimuthal quantum number: shape (0), principal (1), diffuse (2), or FUNDAMENTAL (3).
