Question

What are S block elements. explain their main properties ​

Answer 1

Answer:

S-block elements (except hydrogen and helium) are metals that are shiny, silvery, relatively soft, good conductors and lose electrons easily. Hydrogen and helium are similar to s-block elements in that they have valence electrons in the s orbital. Otherwise, they lack similar properties.

Answer 2

$\huge\tt\colorbox{lime}{Answer}$

The s-block elements of the Periodic Table are those in which the last electron enters the outermost s-orbital.

Properties of S - block elements :

⭐ They are soft metals.

⭐ They possess low melting and boiling point.

⭐ These elements have valence shell electronic configuration either ns¹ or ns²

⭐ They are very reactive and readily forms ionic compounds.

⭐ The alkali metals shows monovalency wheras alkaline earth metals shows divalency.

⭐ They have great affinity for oxygen and non - metals.

⭐ They displace hydrogen from acids and forms corresponding salts.
