Nonmetals are chemical elements that mostly lack distinctive metallic properties. They range from colorless gases like hydrogen to shiny crystals like iodine. Physically, they are usually lighter (less dense) than metals; brittle or crumbly if solid; and often poor conductors of heat and electricity.
May 1, 2024 · Nonmetal is a substance that has low to moderate electrical conductivity and can form negative ions or anions. Learn about the types, properties, and examples of nonmetals, such as carbon, nitrogen, sulfur, and phosphorus, from Britannica.

The nonmetals are located on the upper right side of the periodic table. Nonmetals are separated from metals by a line that cuts diagonally through the region of the periodic table containing elements with partially filled p orbitals. The halogens and noble gases are nonmetals, but the nonmetal element groupusually consists of the following element...
Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily. Nonmetals display a wide range of chemical properties and reactivities.
Here is a summary of the properties of the nonmetals. 1. High ionization energies 2. High electronegativities 3. Poor thermal conductors 4. Poor electrical conductors 5. Brittle solids—not malleable or ductile 6. Little or no metallic luster 7. Gain electrons easily 8. Dull, not metallic-shiny, although they may be colorful 9. Lower melting points ...
The chart below displays a comparison of the physical and chemical properties of the metals and nonmetals. These properties apply to the metals in general (alkali metals, alkaline earth, transition metals, basic metals, lanthanides, actinides) and nonmetals in general (nonmetals, halogens, noble gases).

Apr 28, 2024 · A nonmetal is a chemical element that mostly lacks metallic attributes. Physically, nonmetals tend to be highly volatile (easily vaporized), have low elasticity, and are good insulators of heat and electricity; chemically, they tend to have high ionization energy and electronegativity values, and gain or share electrons when they react with ...
