Nobel gases?

Question

I need to know whats different about nobel gases. something about particles?

why are they called nobel gases?

Answer 1

There are 6 noble gases and they are grouped together in the last column (to the right) of the periodic table (Group 18, which is also called Group VIII and even Group 0).

They are Helium, Neon, Argon, Krypton, Xenon and Radon.

All noble gases are extremely stable because they have the maximum number of electrons possible in their outer shell (2 for Helium, 8 for all others). The noble gases have high ionization energies and negligible electronegativities. They have low boiling points and are all monoatomic gases at room temperature.

At extremely low temperatures, they will become solids (except for Helium, which also requires pressure to solidify). They all form face-centered cubic crystals.

Once considered inert (not capable of reacting), the heavier three can react with Fluorine (the most electronegative element).

Answer 2

The noble gases are the elements in group 18 (Group 0 IUPAC Style) of the periodic table. It is also called helium family or neon family. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable. 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

Noble gases have full valence electron shells. Valence electrons are the outermost electrons of an atom and are normally the only electrons which can participate in chemical bonding. According to atomic theory derived from quantum mechanics and experimental trends, atoms with full valence electron shells are extraordinarily stable and therefore do not form chemical bonds.

All of them exhibit an extremely low chemical reactivity; in fact no conventional compounds of helium or neon have yet been prepared. Xenon and krypton are known to show some reactivity in the laboratory. Recently argon compounds have also been successfully characterised.

The noble gases' lack of reactivity can be explained in terms of them having a "complete valence shell". They have little tendency to gain or lose electrons. The noble gases have high ionization energies and negligible electronegativities.

The noble gases have very weak inter-atomic forces of attraction, and consequently very low melting points and boiling points. This is why they are all monatomic gases under normal conditions, even those with larger atomic masses than many normally solid elements.

Answer 3

Noble gases.

They are more stable than any other kind of elements in the periodic table (in other words, they only rarely react with other elements), because they already have all the electrons that their outer shell can hold.

In order of density, the noble gases are: helium, neon, argon, krypton, xenon and radon.
They are also known as the helium family or the neon family of gases.

Answer 4

They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable. 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.

Answer 5

Noble gases are inert i.e. they do not react with anything. This is because that they have electronic configurations which consist of completely filled sublevels.

Answer 6

Noble gasses are the only elements on the periodic table that dont share a covalent(outer-shell electron) bond with other elements. Meaning that there is no energy transfer between their reactions with other atoms

Answer 7

This because , they are inert so they cannot take part in any reactions.Their outermost Electron Configuration is full of electrons which increases their stability hence making them chemically stable resulting to the name noble. They cannot gain or lose any electrons.
