A reactive metal - say Aluminum, can be veiwed as corrosion resistant - but is actually not. What happens is that pure aluminum actually corrodes extremely quickly. A thin film of aluminum oxide forms on the surface - and it is that film that is extremely adherent but also very corrosion resistant.
Rust on the other hand does not stick (adherent) to iron/steel. It spalls off allowing the iron underneath to corrode further.

What family in the Periodic table contain the most reactive metals?
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
Are gold and platinum reactive metals?
Gold and platinum are less reactive metals but not absolutely non-reactive.
What mental is more reactive than zinc?
There are many metals that are more reactive than zinc. To find out which these metals are, you can look at a reactivity series. Some examples of metals more reactive than zinc are sodium, potassium, magnesium & aluminium.

Vinegar (acetic acid) can react with some reactive metals as alkaline metals.
