The metals and non-metals are separated by a "stair-step" pattern that begins between polonium and astatine and moves up/left to boron. Most periodic tables display this stair-step as a bold line, or a different color, or something else easy to spot. Generally speaking, the metals are everything to the left of the stair-step, and the non-metals are everything to the right. The small handful of elements that "ride" the stair-step are called metalloids. Metalloids can have properties of both metals and non-metals.
