S block elements of the periodic table are made up of
The s-block elements are those in which the outermost electrons occupy the s-orbital. These include elements in Groups 1 and 2, corresponding to the alkali metals and alkaline earth metals. They exhibit similar properties such as high reactivity, the formation of basic oxides and hydroxides, and the tendency to lose electrons to form positive ions. Their general electronic configuration ends in ns1 or ns2.
