They are elements that are in the gas phase under normal temperature and pressure (1 atmosphere of pressure at 273 K).
The gaseous elements are: hydrogen (H2), helium (He), nitrogen (N2), oxygen (O2), fluorine (F2), neon (Ne), chlorine (Cl), argon (Ar), kyrpton (Kr), xenon (Xe) and radon (Rn). Note that some are diatomics and are composed of two of the same atom, while the others are not -- the ones that are not diatomics are all noble gasses
They can be both. The noble gases (far right column of the Periodic Table) are all elements, since they can't form compounds*. But most gases are compounds. A common misconception is that hydrogen gas is an element, but it's not. It's a diatomic compound. You cannot find any of the diatomic gases (H, O, F, Br, I, N, Cl) in their pure form without being diatomic. So with the exception of the noble gases, all gases are compounds.
*with the occasional exception of Xenon, but this is only under very rare conditions and never occurs in nature.
A gaseous element is defined as any element that is a gas at room temperature. For Example, all of the Inert Gases are gaseous elements as they are a gas at room temperature. In total, there are 11 gaseous elements on the Periodic Table.
The last column on the right of the Periodic Table group 18, are the Noble gases. Helium, Neon, Argon, Krypton, Xenon and Radon. They are all nonreactive, inert. There outer electron shells are full and they cannot share. Hydrogen, Nitrogen, Oxygen, Fluorine, and Chlorine are also gases at room temperature. These are mostly very reactive in combination. Hydrogen and Oxygen being very flammable.

Noble gases are elements that generally don't combine with other elements.
hydrogen, helium, neon, argon, krypton, xenon, radon, fluorine, chlorine, oxygen, nitrogen and probably Uuo.
he believed that there was a storm including lighting which split apart the gases and they combined to form new compounds. it also rained which added oxygen to the Earth so when the elements recombined they would have oxygen. theses new compounds were known as amino acids
a compound is made up of 2 or more types of atoms . atoms are smaller. u know what im sayin. listen, chemistry ain't a bowl of lemons . u gata wrk for it brotha
The noble gases: Helium, Neon, Argon, Krypton, Xenon, Radon, all the gases in that chemical group or family. The noble gases do not usually form compounds, except under extreme conditions: high heat and pressure, and then only in the presence of a catalyst, such a platinum [Pt] or nickel [Ni].
Compounds are made up of 2 or more elements.Compounds can be broken down into simpler substances by chemical means, but elements cannot.Compounds are made up of 2 or more elements. Compounds can be broken down into simpler substances by chemical means, but elements cannot.
Elements and compounds
Gases may be elements, compounds, or mixtures. A gas is a phase state of matter.
the noble gases
Noble gases.
Noble gases
No. The noble gases are inreactive and don't form compounds with other elements. This is because they have a full outer shell of electrons.
No, not all gases are elements.
Noble gases do not normally form compounds.
Unlikely other elements in the periodic table, noble gases rarely form compounds with other elements.
Group 18 elements, which are also known as noble gases, rarely form chemical compounds.
I'm guessing noble gases since they do not react with other elements
All gases are made up of elements, but some are not pure elements. Some are compounds, which are not the same as elements. For example, CO2 is a compound and a gas, but not an element.
Some gasses are elements, such as oxygen and nitrogen. Some gasses are compounds of multiple elements put together, such as carbon dioxide.
