Question

Actinides series
Halogen gases
Lanthanide series
Noble gases

Answer 1

Noble Gases are the unreactive gases

Answer 2

Answer: Option (d) is the correct answer.

Step-by-step explanation:

Noble gases are the gases of group 18 which are helium, neon, argon, krypton, xenon and radon.

For example, electronic configuration of neon is
`1s^(2)2s^(2)2p^(6)`

These elements have completely filled shells so, they do not need to gain or lose an electron as they are stabilized.

As a result, noble gases become unreactive in nature.

Thus. we can conclude that noble gases is the name of the group of elements that are unreactive gases.
