1) they are all gases 2) they are all monoatomic
They are the noble gases. They have 8 valence electrons, so that means that they are stable, and they rarely make bonds with any other elements or compounds.
That should be the first two noble gases: Helium and Neon. These two are chemically inert and do not react with anything.
halogens and noble
When two noble gases are combined, they tend to form a stable non-reactive mixture due to their full outer electron shells, which makes them very unlikely to react with other elements. This makes noble gas compounds very rare under normal conditions.
Two noble gases are helium and neon. These gases are odorless, colorless, and generally do not react with other elements due to their fully-filled outer electron shells. They can be found in small quantities in the Earth's atmosphere.
Noble gases are chemically inert.
it's not
There are no metals in noble gases.All are gases in noble gases.
The two abnormal noble gases will be xenon and krypton. Noble gases are generally chemically inert at S.T.P. However, xenon and krypton react with electronegative elements like fluorine and oxygen forming fluorides and oxyfluorides.
All noble gases are gases in their standard state
Yes, except for helium which only two electrons. All noble gases are found under the noble gas family to the far right of the periodic table.
They're all Noble gases.
