Given information

Here we are given the elements chlorine and oxygen, we have to find out which one is more metallic.

Step-by-step explanation

Step 1.
The metallic nature of a metal determines its amount of reactivity. It drops from left to right throughout a period in the periodic table and increases down the group in the periodic table. 
 
Because the metallic character decreases as we progress across the periodic table from left to right, O is found to the left of Cl in the periodic table. 
 
The tendency to lose electrons decreases as the effective nuclear charge acting on the valence shell electrons increases with time. As a result, the metallic character decreases over time while increasing down a group.
