Question

Noble gas is chemically inactive. Explain with reason.

Answer 1

Hint: We should know that the shells of the noble gases are already complete so they need not to share , lose or gain the electrons. This further does not allow them to take part in the chemical bonding and hence, becomes inactive and unreactive.

Complete answer:
We should know that every element atom or the molecule around us takes part in bonding as either they gain, lose or need to share an electron in order to complete the outermost shell that is also called the valence shell . we should know that the shells of the noble gases are already complete so they need not share , lose or gain the electrons. This further does not allow them to take part in the chemical bonding and hence, becomes inactive and unreactive. Further we can conclude that they have completely filled valence shells and the next available shells must be of the higher energy . Also, we can further say that they have a very large positive electron gain enthalpy values. Then we should say that they should also have a very high ionisation enthalpy.
Furthermore discussing it we can say that as we move in a periodic table we generally see that the group one and seven have incomplete outermost shells so they are reactive and that the group zero is complete so that is unreactive. Moreover the noble gases are a very wide concept that is discussed here in brief.
Helium is one of the common examples of the noble gases which is further used as a lifting gas in the party balloons and airships . also it is non flammable so do not catch fire easily.

Note: Some basic properties of the noble gases here include that they have low density and further are non flammable so do not catch fire easily. Noble gases are an interesting topic to be studied about as it has a great application in the industry and everyday life.
