Question

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

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

Answer 1

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

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