Structures of JEE (Main+Advance) Repeater Course s-Block Elements
The structures of s-block elements in the JEE (Main+Advanced) repeater course are determined by their electronic configurations and their position in the periodic table. The s-block elements are located on the left-hand side of the periodic table and include the alkali metals (Group 1) and alkaline earth metals (Group 2).
The electronic configuration of these elements determines their structure. Alkali metals have a single valence electron in their outermost shell, which makes them highly reactive and forms a monovalent cation when they lose an electron. They have a body-centered cubic (bcc) structure, in which the atoms are located at the eight corners and one body center of the cube.
Alkaline earth metals have two valence electrons in their outermost shell, which makes them less reactive than alkali metals. They form divalent cations when they lose two electrons. They have a face-centered cubic (fcc) structure, in which the atoms are located at the corners and on the faces of the cube.
The structure of the s-block elements plays an important role in their physical and chemical properties, such as melting and boiling points, reactivity, and solubility.
