it's not
They are gases that do not form normal chemical bonds with more than a very few other elements.
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
the noble gases, krypton, xenon and radon are larger than bromine
noble gases have larger radius than cations.
No. they are different.
Noble gases have completely filled orbitals and are stable and chemically inert (non-reactive).
Elements such as oxygen, hydrogen, carbon, and nitrogen are not noble gases. These elements are found in different groups of the periodic table and have varying chemical properties compared to the noble gases.
Noble gases are chemically inert.
There are no metals in noble gases.All are gases in noble gases.
oxygen, nitrogen, hydrogen, fluorine
it has no hardness ohk... then what exactly do you call solid oxygen?
All noble gases are gases in their standard state
