Activity series

Activity series Single substitute reactions arise among an detail in an uncombined shape and a compound. The wellknown shape of this response is frequently written as:

Depending on whether or not the uncombined detail is a metallic or a non-metallic, it may update both the compound`s cation or the anion from the preliminary reactants. The merchandise of a a hit unmarried displacement could be a brand new compound and a brand new unbonded detail.

A double displacement response is comparable however has some key differences. In a double displacement, extraordinary compounds are to be had withinside the reactants to probably react collectively in place of a sole unbonded detail as a unmarried substitute could have.

Here is an instance of a unmarried displacement: Zn(s) + 2 HCl(aq) ? ZnCl2(aq) + H2(g). Zinc will be the unmarried unbonded reactant from the definition above.

Here is an instance of a double displacement: BaCl2(aq) + Na2SO4(aq) ? BaSO4(s) + 2 NaCl(aq). There are compounds withinside the reactants to sign the double displacement response.

It may be a treasured talent to are expecting the goods of a response earlier than simply blending the reactants. For safety’s sake, having self belief in the goods of a response earlier than the response takes area may be essential.

The Activity Series of Metals: Activity series

What is pastime collection, and the pastime collection definition? An pastime collection is a device that may be used to make predictions as to whether or not a unmarried displacement response will arise or whether or not there may be no response. The pastime collection of metallic is viable because of the predictable reactivity of an detail primarily based totally on its electron configurations. Elements near complete valence shells (both with the aid of using dropping or gaining valence electrons) have a tendency to be the maximum reactive factors. In addition to valence electrons, the relative length of atoms also can assist are expecting the reactivities of factors inside a collection.

A response among a metallic and a compound is viable because of the assessment among the 2 categories’ configurations. Metal could have a configuration that results in the donation of electrons to finish a valence shell, whilst non-metals are more likely to just accept electrons to fill a valence shell.

Activity Series of Metals Chart: Activity series

Metal in its elemental shape might also additionally or won’t react with an aqueous compound, and the pastime collection of metals can assist make that determination. Take a have a take a observe this pastime collection of metals, with the maximum reactive non-metals indexed on pinnacle:

Activity Series: Activity series

With this collection, potassium is indexed because the pinnacle detail of the group, which means that it’s miles the maximum reactive. Gold is indexed on the bottom, which indicates that it’s miles the least reactive of this group. The better up an detail is at the desk, the greater reactive. This placement may be used to are expecting the incidence of the subsequent unmarried displacement:

This response could arise. This response may be decided with the aid of using evaluating the place of potassium ( the unbonded reactant) with Magnesium (the cation of the compound withinside the reactants). Through using the Activity Series, it may be visible that potassium is better and as a result greater reactive, so it’s going to certainly update the Magnesium, and a response will arise.

If the reactants had been modified barely to this: Activity series

This response could now no longer take area. This response could now no longer react due to the fact the unbonded metallic is decrease at the pastime collection than the cation that it is attempting to update.

What metals are excessive in pastime collection?: Activity series

The Alkali Metals and the Alkaline Earth Metals are each particularly excessive on maximum pastime collection. Specifically, you’ll discover potassium, Sodium, and Calcium close to the pinnacle of maximum lists.

What is the reason of pastime collection of metals?

The pastime collection of metals is a listing of metals so as of reactivity. Elements which might be better up at the listing are greater reactive than the decrease ones at the listing. The listing allows are expecting whether or not factors and compounds will make a response earlier than they’re bodily mixed.

What do you imply with the aid of using pastime collection of metals?

Activity Series of metals is a time period that references a rating of not unusualplace metals in phrases of reactivity. The better up at the listing a metallic is, the greater reactive it’s miles.

How do you study a metallic pastime collection?

When searching on the reactants of a ability response, the metals concerned in every reactant have to be positioned at the pastime collection and compared. If the detail in its elemental shape is better up at the listing than the detail in a compound, the basic metallic will update it, and a response will arise.

How do you expect the goods of a chemical response?

While searching on the reactants only, whether or not a response will arise or now no longer may be decided with the aid of using evaluating the place of the metals withinside the reactants on an pastime collection. If an detail in an uncombined shape is better up at the collection than the blended metallic, the uncombined will update the metallic of the compound and make a brand new compound and a brand new elemental metallic in the goods.

Activity Series Study Guide

The pastime collection is a fixed of metals and non-metals of factors indexed withinside the reducing order in their reactivity. It is likewise referred to as the reactivity collection.


Have you ever questioned why extraordinary metals and nonmetal factors react with every other? Why do a number of the factors withinside the periodic desk now no longer react at all? All of those are very considerate questions. We recognise because of a number of the chemical reactions, all of the factors react to shape new compounds. But, the way to apprehend which factors will react with the opposite or which one will update and take its area?

Well, it may be tough to apprehend how an detail will react and iycos wherein conditions; hence, to recognise the reactivity of metals, the pastime collection is developed.
