Hydrogen is more reactive than Copper, but less reactive than Zinc which is less reactive than Magnesium which is less reactive than Potassium. Potassium is the most reactive of all, relatively speaking.
Aluminium is much less reactive than Lithium.
the s-block elements are highly reactive elements, on the other hand, d-block elements are less reactive than the alkai metals and the alkai-earth metals. some are so reactive that they do not easily form compounds.
Ethers are the least reactive class of organic compounds, moreover they are also less reactive than water
because in table of re-activity of metals it is below zinc
