Answer:

Well the least reactive species is the inert gas neon.

Explanation:

And as for the most reactive, you have an alkali metal versus oxygen gas. AS an alkali metal, lithium is a powerful reducing agent. And oxygen gas is a potent oxidant, and will oxidize most everything on the Periodic Table. So for these two elements, you are comparing apples and oranges.
