Question

Give one word/a few words for each of the following.

Any four noble gases

Answer 1

• Noble gas elements are present in Group 18 of the periodic table.
• These elements are commonly known as inert elements, due to their low reactivity.
• They are the most stable due to having the maximum number of valence electrons their outer shell can hold.
• Therefore, they rarely react with other elements since they are already stable.
• Some noble gas elements are Helium$\left(\mathrm{He}\right)$, Neon$\left(\mathrm{Ne}\right)$, Argon$\left(\mathrm{Ar}\right)$, and Krypton$\left(\mathrm{Kr}\right)$.
