Question

Why were the noble gases and their compounds discovered lated?

Answer 1

The noble gasses are inert or unreactive due to the fact that they all follow the rule of octet and have complete s2p6 orbital arrangements in the highest energy level.Because most elements were discovered through their reactivity with other elements, typically with oxygen, it was difficult for scientists to work with a substance that seemed to have little or no chemical properties based upon the lack of reactivity.

Answer 2

The componds of noble gases were discovered late because most elements were discovered through their reactivity with other elements, typically with oxygen, it was difficult for scientists to work with a substance that seemed to have little or no chemical properties based on the lack of reactivity.
