Transcript:Properties of Nonmetals
Which Elements Are Nonmetals?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. Technically, the halogens and noble gases are nonmetals, but the nonmetal element group usually is considered to consist of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, and selenium.
Nonmetal PropertiesNonmetals 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.
