Given information
Here we are given the elements Strontium and Antimony, we have to find out which one is more metallic.
Step-by-step explanation
Step 1.
The level of reactivity of a metal is defined as its metallic character. It decreases across a period in the periodic table from left to right and increases down the group in the periodic table.
Among Sr(Strontium) and Sb(Antimony), Sr is located on the extreme left, and Sb is located on the right of the periodic table. Since the metallic character decreases as we move across left to right 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 across periods while increasing down a group.
