Nonmetals are a group of elements that lack the characteristics of metals. They are typically poor conductors of heat and electricity and can be found in various states at room temperature, including gases like Oxygen and Nitrogen, and solids like Sulfur and Carbon. Nonmetals play crucial roles in biological processes and are essential for life. In the periodic table, nonmetals are located on the right side, and they include elements such as Hydrogen, Helium, and Chlorine. These elements often form covalent bonds with other nonmetals and can also form ionic bonds with metals. Their diverse properties make them vital in numerous chemical reactions and applications.
