Question

explain why the s-block elements donot exhibit variable valencies​

Answer 1

Answer:

The electrovalency of an element is equal to the number of electrons lost or gained by its atom during the formation of ionic bonds. The s-block elements do not show variable valency. However, p-block elements with higher atomic number transition and inner transition elements show variable valency.
