Nonmetals are elements that typically have high electronegativities and ionization energies, making them more likely to gain electrons during chemical reactions. They are usually poor conductors of heat and electricity and can exist in various states at room temperature (solid, liquid, or gas). Common nonmetals include hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, and the halogens (fluorine, chlorine, bromine, iodine). These elements tend to form covalent bonds and exhibit varying physical properties, such as low density and high volatility.
Atoms of nonmetals tend to be smaller than atoms of metals in the same period.

III only. Nonmetals.
Nonmetals are found to the right.
When nonmetals react with nonmetals, their atoms typically share electrons to form covalent bonds. This sharing allows each atom to achieve a more stable electron configuration, often resembling that of noble gases. As a result, molecules are formed, which can have various physical and chemical properties depending on the specific nonmetals involved.
The nonmetals share the atoms when reacting with each other.

An element that has characteristics of both metals and nonmetals is a metalloid.
No, atoms of nonmetals usually gain electrons when they combine with other atoms. Nonmetals have a tendency to attract electrons to achieve a stable electron configuration, typically by forming covalent bonds with other nonmetals or by gaining electrons to form anions.
III only. Nonmetals.
When nonmetals react with other nonmetals, they typically share electrons to form covalent bonds. This sharing allows the atoms to achieve a full outer energy level and become more stable. The resulting molecules usually have lower melting points and are often gases or liquids at room temperature.

Metalloids
Nonmetals are found to the right.
Yes, metalloids have characteristics of both metals and nonmetals. They have properties that are intermediate between metals and nonmetals, such as being semi-conductive and having a mix of metallic and nonmetallic appearances.
