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

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
Elements that do not ordinarly form compounds are?
Noble gases.
What are elements called that do not form compounds?
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.
Can all elements form compounds?
Compounds are combinations of elements. They are different from molecules in the fact that Compounds cannot be a combination of the same element ( O2 ) instead compounds are combinations of different elements ( CO2 )
What distinguishes noble gases from other nonmetals?
Unlikely other elements in the periodic table, noble gases rarely form compounds with other elements.
How Aluminum iron copper and oxygen are all examples of what compounds mixtures elements gases?
Aluminum, iron, copper, and oxygen are all examples of elements. Elements are pure substances that cannot be broken down into simpler substances by chemical means. They represent the basic building blocks of matter, while compounds and mixtures consist of two or more elements or compounds combined. Gases can be elements, but not all elements are gases; for instance, aluminum and iron are solids at room temperature.
Are all substances elements?
No, substances can be elements or compounds. Elements are pure substances made up of only one type of atom, while compounds are made up of two or more different types of atoms chemically bonded together.
The elements that do not ordinarily form compounds are?
Noble gases, such as helium, neon, and argon, do not typically form compounds because they have a stable electron configuration with a full outer shell of electrons, making them very unlikely to gain or lose electrons to form bonds with other elements.
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.
