Nonmetals are elements on the periodic table that do not fit into the description of metals. Some of the metalloids are sometimes considered to be nonmetals.
Nonmetals can be solids, liquids, or gases. They can be colorless or colored. Many of them are oxidizing agents. Nonmetals react with metals to make salts.
