Question

Place the following in order of increasing metallic character: Na, P, AI, Ar.

Step-by-Step Solution

Answer

The correct order is Ar, P, Al, Na

Step 1: Given Information

We have to place the elements Al, Na, P, Ar in correct order of property metallic character.

Step 2: Explanation

As metallic character decreases as we move left to right and increases down to group and all the metals given are in $3^{rd}$ period but their groups are different.

Na is in $1^{st}$ group, Al is in ${13}^{th}$ group , P is in ${15}^{th}$ group and Ar is in ${18}^{th}$ group.
