the ones at the top are the most reactive.
The Activity Series of metals is a very essential part in predicting the result of many reactions. The Activity series is a chart which list's metals in order of declining reactivity. The metals on the top of the series are the most reactive and the ones in the bottom are the least reactive. The first five elements on the chart are highly reactive metals; which will react with water and steam. It is essential to know, that reactions should be performed in room temperature for the activity series to work well. Many would predict that metals with low ionization energy and lower electro negativity would me more active, because they are more vulnerable to lose electrons in a reaction. However, while these properties do affect an elements place in the series, there are other factors that affect an elements activity
11.2 AnswersIt is possible to predict the products of some chemical reactions. In order to do this, you must be able to recognize at least five general types of reactions. For example, in a combination reaction. the reactants are two or more substances and/or compounds and there is always a single product. In a decomposition reaction, a single compound is broken down into two or more simpler substances. In a single-replacement reaction, the reactants and products are an element and a compound. The activity series can be used to predict whether most single-replacement reactions will take place. A double-replacement reaction involves the exchange of ions between two compounds. This reaction generally takes place between two ionic compounds in aqueous solution. One of the reactants in a combustion reaction is oxygen. The products of the complete combustion of a hydrocarbon are carbon dioxide and water.
An element in the activity series can replace any element below it on the list. The ability of an element to react is referred to as the element's activity.

Yes it is. Calcium atom loses electrons more readily in cell reactions than in reactions with air, water and dilute acids.

An activity series is used to predict whether metals will displace hydrogen gas from water and acid solutions. It is also used to predict whether metals will displace other metals.
_Answer">Metals higher in the series will replace metal ions in solution that are lower in the series. AnswerIn general, the more "reactive" (electro-positive) the metallic element, the more stable will be the compounds it forms with other elements. AnswerThe activity series can be used to predict whether or not a reaction will occur -- in other words, a yes-or-no answer. It cannot be used to predict what the products of the reaction are, which is entirely dependent on the specific reactants. See the Related Questions about cupric sulphate and an iron nail for a good description of how to use the activity series to predict if a reaction will happen or not.
Activity series are useful for single displacement reactions.
A metal replaces a metallic ion below it on the list.
Metals higher in the series will replace metal ions in solution that are lower in the series
An activity series is a list of elements organized according to the ease in which an element can undergo certain chemical reactions.

The product inhibits the activity of the first enzyme
An activity series of metals can predict whether a replacement (displacement) reaction will occur. You use the activity series to compare the reactivity of different metals in order to predict whether a replacement reaction will occur. A metal that is above another metal in the series will replace that metal in a compound.
