Question

how do the noble gases differ from other elements

Answer 1

What differ the noble gases from all the other elements is that the noble gases have a full valence electron energy level which consists in 8 valence electrons

Answer 2

Explanation:

Members of group number 18 of the modern periodic table corresponds to noble gases. For example : neon, helium , argon etc.

The properties of noble gases are:

• These are colorless gases
• These are odorless gases
• These are mono-atomic gases composed of single atom only,
• These gases are inert nature and show low reactivity due to complete filled $ns^2np^6$ electronic configuration in their valence shells.

• They have high ionization enthalpies and positive electron gain enthalpies
