Final answer:
The left side of the periodic table exhibits more metallic character, as metallic character decreases from left to right and increases from top to bottom within the table.
Step-by-step explanation:
The left side of the periodic table is more metallic in character. This is because as you move from left to right across a period, the metallic character decreases. This happens because elements become less willing to lose electrons and more inclined to accept them, thus gaining a more nonmetallic character.
Overall, the most metallic elements are located toward the bottom left of the periodic table. The periodic table is organized such that metals are on the left and nonmetals on the upper right, separated by semi-metals in a diagonal band.
