why do noble gases form compounds with fluorine and oxygen only?
311813
noble gas form compounds with oxygen and fluorine only because they are most electronegative elements. So they can ionise noble gases also.

Answer: An inert gas is one that does not undergo chemical reactions. Noble gases refers to the right most group of the periodic table composed of helium, neon, argon, krypton, xenon, and radon. As you might have seen as an example in class, some noble gases can form chemical compounds, such as XeF4.

Oxygen and argon are both gases. Oxygen combines readily with other elements, but argon does not. What accounts for this difference? Argon is considered to be a noble gas because all of its valence electrons are stable and equal to each other.

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

Other characteristics of the noble gases are that they all conduct electricity, fluoresce, are odorless and colorless, and are used in many conditions when a stable element is needed to maintain a safe and constant environment. This chemical series contains helium, neon, argon, krypton, xenon, and radon.

This is a tendency, not a rule, as noble gases and other "inert" gases can react to form compounds. The group 18 elements include helium, neon, argon, krypton, xenon and radon. They are referred to as noble gases or inert gases.

Oxygen is not a noble gas. Oxygen is a gas in the group 6 of the periodic table which needs 2 more electrons to complete the outermost shell. ... The noble gases are Helium, Argon, Neon, Xenon, Krypton and Radon . These are the only elements that can exist in atomic form without being highly reactive.

The noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odourless, colourless, monatomic gases with very low chemical reactivity.

The noble gases are in Group 18 (8A). They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds.

Only krypton, xenon, and radon are known to form stable compounds. The compounds of these noble gases are powerful oxidizing agents (substances that tend to remove electrons from others) and have potential value as reagents in the synthesis of other chemical compounds.

The noble gases possess a complete valence shell and do not usually attract electrons. The lanthanides and actinides possess more complicated chemistry that does not generally follow any trends. Therefore, noble gases, lanthanides, and actinides do not have electronegativity values.

The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.

Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. ... This is a tendency, not a rule, as noble gases and other "inert" gases can react to form compounds. The group 18 elements include helium, neon, argon, krypton, xenon and radon. They are referred to as noble gases or inert gases.

The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons. Although noble gases do not normally react with other elements to form compounds, there are some exceptions.

Chemical Properties of Noble Gases Noble gases are the least reactive of all known elements. That's because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons.

Noble Gases They are helium, neon, argon, krypton, xenon, and radon. They were once called inert gases because they were thought to be completely inert—unable to form compounds. This is a reasonable belief because the noble gases have a complete octet, making them very stable and unlikely to gain or lose any electrons.

In other words, they have the perfect number of electrons already, and don't need to form alliances with anything. This quality makes noble gases (also called "inert gases") intriguing, but their disdain for interacting with regular matter makes them very hard to detect.
