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.
Most metals are reactive to some extent, but their reactivity varies. Some metals, such as gold and platinum, are less reactive and do not easily tarnish or corrode. Other metals, like sodium and potassium, are highly reactive and must be stored in oil to prevent them from reacting with moisture in the air.
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
one reacts and one doesn't
There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
Some of the fairly reactive metals include sodium, potassium, and magnesium. These metals can react with water or oxygen to form compounds. They are located towards the left side of the periodic table.

Other metals, like sodium and potassium, are highly reactive and must be stored in oil to prevent them from reacting with moisture in the air.
Some are but the most reactive are also non-metals.
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.

The alkali metals are more reactive.
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
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.
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.

Reactive metals lose electrons when being oxidised.
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
