Question

Valency of S-block element is ?​​

Answer 1

Elements in column 2 have two valence electrons. S-block elements are very reactive. Elements in column 1 (the alkali metals) always lose their one valence electron to form a +1 ion. Elements in column 2 (the alkaline earth metals) always lose their valence electrons to form +2 ions.
