Iron rusts with water
the more reactive metals react for the oxygen in a displacement
the less reactive metals there is no reaction
hope this helps x
Francium is the most reactive metal in water, but if you're looking for something you can actually access, try potassium or calcium.
The alkali metals lithium, sodium, potassium, rubidium, and cesium are all very reactive toward water. Sodium is the best known of these.
Group 1 metals
Manganese is not particularly reactive. This is strange considering it is more electropositive than its neighbors in the periodic table.
water
A very reactive metal can react too violently with acids to be safe.
Caesium. Francium may be more reactive but it is radioactive as well as chemically very reactive and so there are many uncertainties regarding its properties.
There are many different kinds of metal. There are highly reactive metals such as sodium, which if placed in water will react immediately, forming a sodium hydroxide solution and releasing hydrogen gas. There are moderately reactive metals such as iron, which if placed in water will slowly start to rust. And there are non-reactive (or inert) metals such as gold, which if placed in water don't do anything. Metal + Water (H2O) produces → Metal Hydroxide (OH-) and Hydrogen gas (H2).
"very reactive"
Francium is reactive when your skin is moist because it is very reactive with water. Francium is an alkali metal and is very reactive and violent with water.
Yes sodium is very reactive metal.Just because of this it is kept in kerosene or some another oil because it is very reactive with oxygen and water.
Sodium is indeed very reactive with water because it is an Alkali metal. These metals have low melting points. Like the sodium, they are soft enough to be cut with a knife. They are highly reactive.
Cesium is the most chemically reactive metal.
Carbon is a very reactive nonmetal but not the most reactive.
Manganese is not particularly reactive. This is strange considering it is more electropositive than its neighbors in the periodic table.
water
It is very reactive with water, even moisture in the air, so we store Na metal in paraffin oil.

Actinium is a very reactive (but not the most) metal; the Pauling electronegativity is 1,1.
