At extremely high pressure and/or low temperature, elements that are normally a gas can become liquid.
No. Both are noble gases and do not combine with each other
Argon and helium are both noble gases, which are generally inert and do not readily form chemical bonds with other elements. Therefore, argon and helium do not typically form chemical compounds with each other or with other elements.
Yes, helium, argon, and neon are considered inactive gases because they are chemically inert, meaning they do not readily react with other elements to form compounds. They are also known as noble gases.
When helium and argon are mixed together, they form a homogeneous mixture known as a gas blend. The properties of the gas blend will depend on the ratio of helium to argon in the mixture. Helium is lighter than argon and less soluble in liquids, so it tends to rise to the top of the mixture when not in a pressurized container.
The noble gases are extremely stable and have an octet (eight electrons in their outer shell with the exception of helium that has two). The far right group on the periodic table contains the noble gases such as helium, neon, argon, krypton, etc.
Among neon, argon, and helium, neon is the most reactive because it tends to form compounds with other elements under extreme conditions. Helium and argon are noble gases and are generally unreactive due to their stable electronic configurations.
Helium, neon, argon, krypton, xenon, and radon are inert gases that can form compounds, primarily with highly electronegative elements such as fluorine and oxygen.
When neon, argon, and helium are combined, they form a mixture of noble gases. These gases are colorless, odorless, and generally inert. The resulting mixture would not undergo any chemical reactions with each other.
Noble gases (e.g. helium, neon, argon) are least likely to form bonds due to their stable electronic configuration. Other elements like fluorine and chlorine, which have a full valence shell and do not need to gain or lose electrons, are also unlikely to form bonds. Finally, elements with completely filled valence shells, such as carbon in diamond form, do not readily form bonds.
Hydrogen is the most chemically reactive among the elements listed. It readily reacts with other elements to form compounds, while helium, argon, and neon are inert gases and generally do not undergo chemical reactions under normal conditions.
Potassium can not combine with noble gases, such as helium, neon, and argon, as they are already stable and do not readily form compounds with other elements.
None No compound of He and Ar is known- or even suspected.
