Noble gases are the elements which do not usually interact with other elements.
Step-by-step explanation:
The elements present in the last column of the periodic table defined as noble gases are the elements which do not interact with other elements.
The elements present in the noble gas series have fully occupied valence orbital and thus they are highly stable and does not undergo any kind of chemical reaction with other elements.
They are also termed as inert gases.
They are mostly used as ionizing gases as they can ionize the other gases easily.
