Which list of elements is only nonmetals?

Nonmetals are located on the far right side of the periodic table, except hydrogen, which is located in the top left corner. The 17 nonmetal elements are: hydrogen, helium, carbon, nitrogen, oxygen, fluorine, neon, phosphorus, sulfur, chlorine, argon, selenium, bromine, krypton, iodine, xenon, and radon.

Which element is a nonmetal?

Seventeen elements are generally classified as nonmetals; most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

  • Hydrogen (sometimes considered an alkali metal)
  • Carbon.
  • Nitrogen.
  • Oxygen.
  • Phosphorus.
  • Sulfur.
  • Selenium.

Where are nonmetals found on Earth?

The Earth’s crust, atmosphere, and oceans are constituted mostly of nonmetals and their compounds. Moreover, the bulk tissues of living organisms are composed mainly of nonmetals and their compounds.

Which nonmetals are found in Earth’s crust?

OxygenComplete step-by-step answer: The most abundant non-metal found in the earth’s crust is Oxygen.

What do nonmetals have in common?

Nonmetals share many similar properties including: They are either gas (hydrogen, oxygen, nitrogen) or solid (carbon, sulfur) under standard conditions. They are not good conductors of electricity or heat. They are very brittle in their solid form.

What are some characteristics of non-metals?

In the elemental form, non-metals can be gas, liquid or solid. They aren’t shiny (lustrous) and they don’t conduct heat or electricity well. Usually their melting points are lower than for metals, although there are exceptions. The solids usually break easily, and can’t bend like metals.
