Question

Correct order of metallic character is:

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

Answer 1

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

On going down a group, metallic character of elements increases.

On moving from left to right in a period, metallic character of elements decreases.

Hence the correct order is,

$P<Si<Be<Mg<Na$
