S Block Elements - Properties, Periodic Trends, Configurations
WEBThe elements of Group 1 and Group 2 of the modern periodic table are called S-block elements. Two types of s block elements are possible, i.e., the elements with one electron (s1) or the elements with two electrons (s2) in their s-subshell.

WEBSep 21, 2020 · Periodic table blocks are sets of elements grouped by their valence electron orbitals. The four block names are s-block, p-block, d-block, and f-block. Should a new element be discovered, it will be in g-block. Each block indicates which electron sublevel is in the process of being filled.
