Nonmetals are primarily located in the upper right-hand corner of the periodic table.

While the majority of elements are classified as metals—which occupy the left side and center of the table—nonmetals are relatively few in number. A notable exception to their placement is hydrogen, which is a nonmetal located in Group 1 on the far left of the table. Additionally, it is important to note that the division between metals and nonmetals is approximate; elements found along the dividing line that exhibit properties of both are known as metalloids.1
