There is different ways.
Either you make an experiment yourself by reacting the different metals with a substance and then stopping the time it took for each reaction to stop ( quicker = more reactive)
Or you can use already done experiments and look for your metal in there.
Also there are columns of reactivity for metals. These tell you which metals are more reactive. The more reactive ones are the ones that are going to react faster. THis can be essential when choosing the right metal for a reaction.

What is the rarest metal in the earth's crust?
The rarest metal in the Earth's crust is believed to be rhodium. It is a platinum group metal that is scarce in nature and often found in association with other platinum group metals. Rhodium is primarily sourced as a byproduct of platinum and palladium mining.
What characteristics does pure sodium have?
Pure sodium is a metal. It bonds fairly easily with halogens (such as chlorine, to make table salt), and it reacts quite violently when put in contact with water (explodes). Other than that, I don't know too many specifics about pure sodium, so if anyone would like to take it from here, feel free.
What is the classification of nickel?
Nickel is a transition metal in Group 10 of the periodic table.
How do you extract metal from its oxide?
Metal can be extracted from its oxide by a process called reduction. This involves using a reducing agent such as carbon or hydrogen to remove the oxygen from the metal oxide. The metal is then left in its elemental form.
Which element is more likely to combine with other elements calcium or xenon how do you know?
Calcium is more likely to combine with other elements because it is a metal with a tendency to lose electrons to form positive ions, while xenon is a noble gas with a stable electron configuration and tends to not form chemical bonds with other elements.
Viruses multiply the same way as other organisms?
I don't know about the same as other organisms,but definitely faster!MUCH faster!
Which metal is green in colour?
As far as i know there is no green metals. The green hue comes from copper and pxygen reacting and becoming copper oxide, which has a green tint (like the statue of liberty
How do you know if sodium is chemically reacting?
You know when sodium is chemically reacting when you see bubbles or any weird thing going on....something thats happening that wasn't happening till now. (:
You are doing a project on coke acid what should you know?
Try working out the pH, the acidity. You can try adding indicators to it, or you can try reacting coke with a reactive metal such as magnesium ribbon. Or, you could try the coin trick... :)
How do you know something is moving faster than some other object?
Calculate the average velocity for the objects.
Why are proteins biologically significant?
All life as we know it consists of proteins (in solution) reacting to their environment.
How do you know when a blackbird is dead?
If it's lying on the ground, not reacting if you come close or doesn't seem to be breathing (Also stiff and cold). basically, every other symptoms you would see in other dead animals.
Why is it important to faster friendship with friends with other country?
because they can teach you things you probably did not know and teach you a different language
How can you rap faster?
The key is to know what you're saying. Once you got that down, you practice rapping it faster and faster until you have the entire thing memorized and you can let it slide off your tongue as fast as you can talk. One way of practicing is reciting other songs you know by heart as fast as you can. If you can talk fast, you can rap fast, and if you know what your saying, it flows much easier. Hope this helped.
Can A boat swim faster then a humen?
Yes. I don't know of a human that can swim faster than a boat. You should know this.
Which molds faster grapes or strawberries?
The strawberry will mold faster than the grape, I don't know why exactly, but I just know it does.
