Nonmetals are located on the right side of the periodic table, with the exception of hydrogen (H), which is a nonmetal and located on the top left corner of the table.

Here's a more detailed breakdown:

* Rightmost Column (Group 18): This entire column is filled with noble gases, all of which are nonmetals.

* Groups 17 (Halogens), 16 (Chalcogens), 15 (Pnictogens), and 14 (Tetrels): These groups contain a mixture of nonmetals and metalloids. Generally, the elements higher up in these groups are nonmetals.

* Hydrogen: As mentioned before, hydrogen is a nonmetal despite being located on the left side of the table.
