Metallic character increases as you move down a group (column) and left across a period (row) on the periodic table.

Here's why:

* Down a group: Electrons are further from the nucleus, making them easier to lose and therefore more metallic.

* Left across a period: Elements on the left have fewer valence electrons, making it easier to lose them and exhibit metallic character.

Key takeaway:

The most metallic elements are found in the bottom left corner of the periodic table.
