Reactivity Of Metals

Reactivity is a term used in chemistry which refers to the rate at which a substance undergoes a chemical reaction. It could be the chemical reaction of only one substance or the reaction of two ormore substances, which react among them, between other functions reactivity uses. How fast a reaction goes is called reactivity rate. A way to find out the reactivity rate is to measure how fast theproduct is made. When particles collide reactions occur, changing the conditions makes them go faster.

In metals it is common that some metals react more easily than others. The more quickly theyreact the more gas is given off.
The substances in which the most reactive metals react are: Acids, Oxygen and Water. The most common reactive metals group is the Alkali. In the periodic table ofelements, we can see there are metals which are more reactive than others. Some metals are more reactive than others; they are put in an order of reactivity which starts with the most reactive, thisis called the reactivity series. “As we go down the reactivity series from potassium to gold the ease with which a metal loses electrons, and forms positive ions in solutions, decreases.” This meansthat electrons are very important for the reactivity of metals. The most active metal is in the top; it is potassium and less active metals is called platinum. We can also find Hydrogen in thereactivity series, although it is not a metal, it reacts as a metal in many of the chemical reactions. For example the hydrogen ion has a positive charge [H+] like other known metals. Reactivity series isvery important and of really great use, because it helps to know which metals, are for reactant, and to understand how they will react, or how they are reacting.

The most reactive a metal is itmeans, the faster the chemical reaction will be and it will be exothermic. But also the most reactive, are the ones who are more difficult to take from its ore.

An ore is the source where the...
