Nonmetals List (Element Groups)

Elements in the Nonmetal Group

The highlighted elements of this periodic table belong to the nonmetal element group. However, halogens and noble gases are also types of nonmetals.

The nonmetals are a group of elements located on the right side of the periodic table (except for hydrogen, which is on the top left). These elements are distinctive in that they typically have low melting and boiling points, don't conduct heat or electricity very well, and tend to have high ionization energies and electronegativity values. They also don't have the shiny "metallic" appearance associated with the metals.

The nonmetals tend to gain electrons readily to fill their valence electrons shells, so their atoms often form negative-charged ions.

List of Nonmetals (Element Group)

Here is a list of elements that are considered to belong to the nonmetals group:

Hydrogen (sometimes considered an alkali metal)

Carbon

Nitrogen

Oxygen

Phosphorus

Sulfur

Selenium

Although these are the elements in the group nonmetals, there are actually two additional element groups that could be included, since the halogens and noble gases also are types of nonmetals.

List of All Elements That Are Nonmetals

So, if we include the nonmetals group, halogens, and noble gases, all of the elements that are nonmetals are:

hydrogen (sometimes)

carbon

nitrogen

oxygen

phosphorus

sulfur

selenium

fluorine

chlorine

bromine

iodine

astatine

element 117 (sometimes considered a halogen, sometimes considered a metalloid)

helium

neon

argon

krypton

xenon

radon

element 118 (possibly will behave as a "noble gas", except it probably won't be a gas)
