Images of the 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.

Properties

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.

Summary of Common Properties

  • High ionization energies
  • High electronegativities
  • Poor thermal conductors
  • Poor electrical conductors
  • Brittle solids
  • Little or no metallic luster
  • Gain electrons easily

Phosphorus Allotropes

Pure phosphorus exists in several forms called allotropes.
Photos of the Nonmetals Pure phosphorus exists in several forms called allotropes. This photo shows waxy white phosphorus (yellow cut), red phosphorus, violet phosphorus and black phosphorus. The allotropes of phosphorus have markedly different properties from each other. BXXXD, Tomihahndorf, Maksim, Materialscientist (Free Documentation License)
