Atomic radius decreases from left to right in a period.
Atomic radius increases down the group of a periodic table.
P and Cl belongs to same period but Cl is placed at right of P
in periodic table .
So atomic radium of Cl is less than that of P.
Ba is at left of periodic table and down the group
So Ba atomic radius is higher than P.
Correct order is Cl
