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

∙ 13y agoThey 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.

∙ 12y agoA 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.

∙ 14y agoThe 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.

What did Oparin believe caused the early gases of Earth to combine?
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
Compare and contrast elements and compounds?
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
What does not react naturally with elements?
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].
How do compounds differ from elements?
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.
Metal compounds made of two or more metallic elements are known as?
Metal compounds made of two or more metallic elements are usually called ALLOYS. However, there are true compounds and these are often known simply as inter-metallic compounds.
Are gases elements?
Gases may be elements, compounds, or mixtures. A gas is a phase state of matter.
What are gases that do not form compounds with other elements called?
the noble gases
What are elements called that do not form compounds?
Noble gases
Elements that do not ordinarly form compounds are?
Noble gases.
Are the Noble Gases very reactive with other elements and form many compounds?
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.
Are all the gases elements?
No, not all gases are elements.
The elements that do not ordinarily form compounds are?
Noble gases do not normally form compounds.
What distinguishes noble gases from other nonmetals?
Unlikely other elements in the periodic table, noble gases rarely form compounds with other elements.
Which group in the periodic table contains elements that do no react easily to form chemical compounds?
Group 18 elements, which are also known as noble gases, rarely form chemical compounds.
What group or family never appears in the elements forming the mineral compounds?
I'm guessing noble gases since they do not react with other elements
Are all substances 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.
The elements are gases?
Some gasses are elements, such as oxygen and nitrogen. Some gasses are compounds of multiple elements put together, such as carbon dioxide.
