Their outer energy levels are completely filled.
What else can I help you with?
How come noble gases do not form compound readily?
Their outer energy levels are completely filled.
Which group of elements is very stable and nonreactive?
Noble gases are the group of elements that are very stable and nonreactive due to their full outer electron shells, which gives them little tendency to gain, lose, or share electrons to form chemical bonds.
All the elemental gases except for the Noble Gases come in what kind of special molecules?
All the elemental gases except for the noble gases come in molecules that are unstable. The noble gases are all stable, they have the maximum number of valence electrons that their outer shell can hold.
How come atoms of noble gases don't form ions?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds / ions under normal conditions.
Why do noble gases not react with other compounds and elements?
Noble gases don't react with other elements because of the stability of the outer hell. Helium has 2 electrons , 1s2 a full shell. the restt have an outer shell of 8 electrons the "octet". This gives neon a full valence shell, the rest of the heavier noble gases have an outer shell with 8 electrons which while it is is very stable and makes these gases very un-reactive it is not full.Compounds have been made for the noble gases heavier than neon. These compounds are all unstable and highly reactive and the first a xenon fluoride was made in 1962.
How come noble gases don't form covalent bonds?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements) and generally don't form covalent compounds
What 3 compounds come out of volcanoes which are gases?
The three main gases that come out of volcanoes are water vapor, carbon dioxide, and sulfur dioxide. These gases are released during eruptions and contribute to the volcanic activity and the formation of volcanic clouds.
Are ionic compounds or covalent compounds more soluble in water Why?
Ionic compounds are generally more soluble in water than covalent compounds because ionic compounds dissociate into their constituent ions when they come into contact with water, forming ion-dipole interactions with water molecules. Covalent compounds do not readily dissociate in water, making them less soluble.
On the periodic table that is a family?
metaloids, halogens, metals, noble gases, carbon family and i think nitrogen family... there are more but these are the first that come to mind
Why can gasses be easily liquefied?
easily liquifiable gases like Cl2, NH3,SO2,HCl are readily adsorbed because the critical temp of these gases are more. so it is easily liquified and adsorbed more readily.[critical temp is the minimum temp above which a gas cannot be liquified]easily liq. gases possess greater vanderwaals forces ,so they are adsorbed readily.these are the 2 reasons why these gases are readily adsorbed than permanent gases like H2, O2.N2 . etc
What periodic elements always come with a partner?
I am not sure entirely what you mean but there are lots of elements that go around in pairs, e.g hydrogen, oxygen, nitrogen amongst others.
Where do the gases come from in the acid rain?
the gases come from factories
