Why are elements of the Noble gases very unreactive? Explain.?

Answer 1

because they have all their valence electrons and are "happy". in other words, their last electron shell is full and they have no "desire" to give or take electrons, making them unreactive.

Answer 2

The noble gases are the elements in group 18 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.

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 electro negativities. 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

Because they're noble snobs who won't get along with others, of course!

Electrons whiz around atoms in cloud patterns called orbitals. Each orbital can hold a specific number of electrons. If an orbital has the maximum number of electrons (e.g. 2 in any "s" or spherical orbital and 6 in the three combined "p" or dumbbell-shaped orbitals), the energy of the clouds is at its lowest point.

This is relevant because a noble gas has full electron clouds. It has to open new orbitals farther away from the nucleus to add electrons (huge energy cost) or give up an electron in a full orbital to react with something (again, energy cost is high). That energy has to come from somewhere, so unless the molecule is very hot or is holding onto its electrons very loosely (i.e. the outer shell is level 4 or 5), it isn't going to happen.

Answer 4

They are very unreactive because they have all 8 of their valence electron slots filled, therefore, they require no other elements to help them to have all 8 of their valent electrons to be stable and "happy"

Answer 5

They are very unreactive because.. the outermost shell is full of electrons.
So, this means .. that the atom doesnt need anymore elecrtons, its unreactive.. so it has no charge.

Answer 6

Because they have a full set of valence electrons. They won't share, donate or accept electrons from any other elements.

Answer 7

becoz there valence electrons r filled with 8 eelectrons and they dont react with many metal except flourine.
