01

Given Information

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

02

Explanation

As metallic character decreases as we move left to right and increases down to group and all the metals given are in 3rdperiod but their groups are different.

Na is in 1stgroup, Al is in 13thgroup , P is in 15thgroup and Ar is in 18thgroup.
