Define s block in chemistry
WebSep 3, 2024 · In chemistry and physics, the main group elements are any of the chemical elements belonging to the s and p blocks of the periodic table. The s-block elements are group 1 ( alkali metals) and group 2 ( … A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-block, p-block, d-block, f-block and g-block. The block names (s, p, d, and f) are derived from the spectroscopic notation fo…
