Question

Arrange the following elements in the increasing order of their metallic character.
$Mg,Ca,K,Ge,Ga$

• A. $Ga<Ge<Mg<Ca<K$
• B. $Ge<Ga<K<Mg<Ca$
• C. $Ge<Ga<Mg<Ca<K$
• D. $Ge<Ca<Ga<Mg<K$

Answer 1

The correct option is C $Ge<Ga<Mg<Ca<K$

The increasing order of the metallic character is:

$Ge<Ga<Mg<Ca<K$ .

Alkali metals are the most electropositive elements and have maximum metallic elements. Alkaline earth metals have the next highest metallic character. p block metals have the lowest metallic character.
In a period, on moving from left to right, the metallic character decreases. In a group, on moving from top to bottom, the metallic character increases.
