State the characteristics of s-block elements. – InterviewSolution

1.	State the characteristics of s-block elements.
Answer» The s-block contains the elements of group 1 (alkali metals) and group 2 (alkaline earth metals). They occur in nature only in combined state as they are reactive elements. Except Li and Be, compounds formed by all other s-block elements are predominantly ionic in nature. This is because they have only one or two valence electrons which they can lose readily forming M⁺ or M²⁺ ions. Since they can lose electrons easily, they have low ionization enthalpies, which decreases down the group resulting in increased reactivity.
