Question

Arrange the following elements in the increasing order of their metallic character.
$Si,Be,Mg,Na,P$

• A. $Na<Mg<Be<Si<P$
• B. $P<Si<Be<Mg<Na$
• C. $Si<Be<Mg<P<Na$
• D. $Si<Be<P<Mg<Na$

Answer 1

The correct option is B $P<Si<Be<Mg<Na$

Metallic character increases down a group and decreases from left to right across a period. Hence, the order of increasing metallic character is $P<Si<Be<Mg<Na$.
