the block names (s, p, d and f) are derived from the spectroscopic notation for the associated atomic orbitals: sharp, principal, diffuse, and fundamental.

there is an approximate correspondence between this nomenclature of blocks, based on electronic configuration, and groupings of elements based on chemical properties. the s-block and p-block together are usually considered main-group elements, the d-block corresponds to the transition metals, and the f-block encompasses nearly all of the lanthanides (like lanthanum) and the actinides (like actinium).
