which elements on the periodic table are gases?
26063
Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).

Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

An element is a substance completely made up of one atom. Thus, the periodic table of elements is effectively a list of all known types of atoms. However, the atom itself is not the smallest known particle, but instead each atom is made up of three individual parts: electrons, protons and neutrons.

Neon Element Facts. The chemical element neon is classed as a noble gas and a nonmetal.

['They are inert gases located on the right of the periodic table.', "They have a full-set of valence electrons, so they're stable.", 'They are colorless, odorless and tasteless.', 'They have low melting and low boiling points.', "They can be found in small amounts in the Earth's crust and the Earth's atmosphere."]

Hydrogen, H, is a highly flammable gas (H2)and the most common component of the universe. It is the lightest element ever and is colorless, odorless, and tasteless. ... It's also the most abundant chemical element on the periodic table. Hydrogen(H) is a gas, and is the first element on the periodic. table.

The periodic table on the left separates elements into three groups: the metals (green in the table), nonmetals (orange), and metalloids (blue). Most elements are metals. They are usually shiny, very dense, and only melt at high temperatures. Their shape can be easily changed into thin wires or sheets without breaking.

Properties. Gaseous chemical element, symbol: He, atomic number: 2 and atomic weight 4,0026 g/mol. Helium is one of the noble gases of group O in the periodic table. It's the second lightest element. The main helium source in the world is a series of fields of natural gas in the United States.

Helium is the second element on the periodic table. ... This group contains the noble gases, which are the most chemically inert elements on the periodic table. Each He atom has two protons and usually two neutrons and two electrons.

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.
1037651
The group 18 elements include helium, neon, argon, krypton, xenon and radon. They are referred to as noble gases or inert gases.
805667
The noble gases are the elements in group 0 of the periodic table. They all have a full outer electron she'll. This is the most stable arrangement of electrons which other elements only achieve by making ions or sharing electrons in covalent bonds. This is why the noble gases are inert, compared with other elements.
