Nonmetals are generally located on the right side of the periodic table. This arrangement reflects their distinct chemical properties, which are characterized by their lack of metallic characteristics, such as malleability, ductility, and good conductivity of heat and electricity. Instead, nonmetals tend to gain electrons during chemical reactions, forming anions or covalent compounds.

In the context of the periodic table, nonmetals include elements such as hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, and the noble gases. They occupy the upper right portion of the table, mainly in groups 14 to 18. The positioning of nonmetals in this area is significant because it differentiates them from metals, which dominate the reactivity and conductivity found on the left and along the middle of the periodic table. Other groups such as the alkali metals and alkaline earth metals are more prevalent in the left portions, while transition metals fill the center. This structural arrangement visually and systematically showcases the contrasting properties of nonmetals as compared to metals and metalloids.
