This page Elements can be solid, liquid, or gas at room temperature. Some periodic tables show this by use of a color code or other key. Neon is a gas at room temperature. Neon belongs to a family of elements that are all gases at room temperature. They are referred to as the noble gas family. There are eleven elements that are gaseous at room temperature. They include: hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon. There are three elements that are liquids at room temperature and they include mercury, gallium, and bromine. The rest of the natural elements (76) are solid at room temperature.

10.1 Gaseous Elements and Compounds Thus, half of the halogens, all of the noble gases, and the lightest chalcogens and picnogens are gases. Of these, all except the noble gases exist as diatomic molecules. Only two elements exist as liquids at a normal room temperature of 20°C–25°C: mercury and bromine.

Noble Gases List While helium and neon are practically inert and are gases, the elements further down the periodic table more readily form compounds are are more easily liquefied. With the exception of helium, all of the names of the noble gas elements end with -on. Here is a list of the elements in the noble gas group: Helium (He, atomic number 2) is an extremely light, inert gas at room temperature and pressure. The liquid form of the element is the only liquid known to man that cannot be solidified, no matter how low the temperature drops.

- The elements that are gases at room temperature include hydrogen. They also include all the inert or noble gases, which are those elements in Group 18: helium, neon, argon, kr…ypton, xenon and radon. We also know that the halogens fluorine, chlorine and bromine are gases at room temperature (20°C). That leaves nitrogen and oxygen as the last of the elements that are gases at room temperature. All of these elements are nonmetals or halogens or inert gases. LAUGH OUT LOUD.

Noble Gases Properties, Uses and Sources By Anne Marie Helmenstine, Ph.D. Learn about the properties of the noble gas group of elements: Location of the Noble Gases on the Periodic Table. The noble gases, also known as the inert gases, are located in Group VIII of the periodic table. Group VIII is sometimes called Group O. The noble gases are helium, neon, argon, krypton, xenon, radon, and ununoctium. Noble Gas Properties. The noble gases are relatively nonreactive. This is because they have a complete valence shell. They have little tendency to gain or lose electrons.

Atom The standard state of a chemical substance is its phase (solid, liquid, gas) at 25.0 °C and one atmosphere pressure. This temperature/pressure combo is often called room conditions.. Two elements are liquid in their standard state: mercury and bromine. Eleven elements are gas in their standard state.

The Noble Gases and Halogens The noble gases. This group contains helium, neon, krypton, xenon and radon. They are different to elements belonging to other groups due to their resistance to form compounds. The reason behind their unreactivity is their full outer shells that give stability to the atoms.

What are noble gases and where on the periodic table are they? Noble gases are elements that have all possible electron positions in the outer, or valence, shell filled. This makes them chemically non-reactive. They are found in group 18 on the periodic table (far right edge) of elements: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).

Noble gas Noble gas. The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable. Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment.
