* Metals: Located on the left side and in the middle of the periodic table. This includes the majority of the elements, with the exception of hydrogen (H), which is a nonmetal.
* Metalloids (Semimetals): Found along the stair-step line that separates the metals from the nonmetals. These elements have properties of both metals and nonmetals.
* Nonmetals: Located on the right side of the periodic table. This includes the gases (like oxygen, nitrogen, and chlorine) and some solids (like carbon, sulfur, and phosphorus).
