What are the characteristic of s-block elements

1.	What are the characteristic of s-block elements
Answer» Characteristics of s-block elements: (i) The s-block elements are metals. These metals are soft, and have low melting and boiling points. (ii) The general outer electronic configuration of the s-block elements is ns^1-2 (iii) These elements are highly electropositive. They lose their valence electrons to form monovalent or divalent cation. For example. M (Li, Na, K, Rb, Cs) → M⁺ (Li, Na, K, Rb, Cs) + e^- and M (Mg, Ca, Sr, Ba) → M²⁺ (Mg, Cu, Sr, Ba) + 2e^- (iv) These elements act as strong reducing agents. This is because, these elements are highly electropositive, and lose electrons readily. (v) The s-block elements mostly form ionic compounds, for example, NaCl, KCl, CaCl₂, etc, are typical ionic compounds.

Characteristics of s-block elements:

(i) The s-block elements are metals. These metals are soft, and have low melting and boiling points.

(ii) The general outer electronic configuration of the s-block elements is ns^1-2

(iii) These elements are highly electropositive. They lose their valence electrons to form monovalent or divalent cation. For example.

M (Li, Na, K, Rb, Cs) → M⁺ (Li, Na, K, Rb, Cs) + e^-

and M (Mg, Ca, Sr, Ba) → M²⁺ (Mg, Cu, Sr, Ba) + 2e^-

(iv) These elements act as strong reducing agents. This is because, these elements are highly electropositive, and lose electrons readily.

(v) The s-block elements mostly form ionic compounds, for example, NaCl, KCl, CaCl₂, etc, are typical ionic compounds.
