Which metal is most reactive?
Francium is most reactive element in periodic table. However, francium is artificial or only few quantities have produced right now, so after the francium, cesium is most reactive metal.
Where is the most reactive metal on the periodic table?
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
What are the 4 most reactive metals?
Explanation: Alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). As you move down the column, the metals become more reactive because the nucleus gains more electrons and protons (more electron levels), weakening their electrostatic force.
What are the top 10 most reactive metals?

Lead is located in the carbon group. Melting point is 625 degrees Fahrenheit. It's symbol is Pb. ...
What is the order of reactivity of metals?
Na > Ca > Mg > Al > Zn > Fe > Sn > Pb > Cu > Ag.
Which metal is most reactive and why?
Caesium, the most reactive metal in the periodic table, reacts extremely violently – hence why it can't be demonstrated in a classroom! This can be compared to other common metals, such as iron and copper, which produce no reaction when dropped into water.
Which element is most reactive?
Fluorine: The Most Reactive And Indispensable Chemical Element In Our Daily Lives. Fluorine is a remarkable chemical element - not only because of its unique reactivity.
What is the least reactive metal?
PlatinumThe least reactive metals would be Platinum, Gold, Palladium, Osmium and Silver and in the decreasing order.
Is copper the most reactive metal?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions ....The reactivity series.ElementReaction with dilute acidsCopperVery slowlySilverBarely reactsGoldDoes not react4 more rows
Which is more reactive iron or copper?
Iron is more reactive than copper as copper has less outer shells than iron, so copper is less likely to react with another element as it has a stronger hold over the electrons.
What are the 2 most reactive groups on the periodic table?
The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons.
Which metal is more reactive iron or zinc?
Zinc more reactive than iron. The reason are: Zinc is a more electropositive element than iron. Zinc has a bigger atomic size than that of iron and thus has more number of electrons.
What is the 2nd most reactive metal?
The alkaline earth metals are the second most reactive family of elements. Beryllium, magnesium, calcium, strontium, barium and radium are all shiny, and silvery-white.
Which metal is most reactive in group 1?
franciumReactivity of Group 1 Elements The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive. Because alkali metals are so reactive, they are found in nature only in combination with other elements.
What are the most reactive elements in order?
The reactivity series follows the order, from most reactive to least reactive:Cesium.Francium.Rubidium.Potassium.Sodium.Lithium.Barium.Radium.More items...•
Where are the most reactive nonmetals on the periodic table?
Answer and Explanation: The most reactive nonmetals are the halogens (of group 17), which are located on the far right-hand side of the periodic table, just before the noble... See full answer below.
How much francium is in the Earth's crust?
There is never enough francium with which to experiment because its isotopes have a very short half-life (the longest is about 22 min), and there is only about 20-30 grams in the earth's crust at any given time. http://education.jlab.org/itselemental/ele087.html
Is cerium reactive?
Cesium is present in large enough amounts to be studied, and experimentally it is the most reactive metal.
Which element is less reactive?
The elements in the periodic table known as the transition metals are much less reactive, and metals such as gold and platinum endorse the bottom of the list, exhibiting less in the way of chemical reaction with any ordinary reagents.
What is the reactivity series of metals?
The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. The data provided by the reactivity series can be used to predict whether a metal can displace another in a single displacement reaction. It can also be used to obtain information on ...
What is the long tabular form of the Reactivity Series?
Long Tabular Form of the Reactivity Series. The reactivities of metals are tabulated below (in the descending order) along with their corresponding ions. Note that the metals in Red react with cold water, those in Orange cannot react with cold water but can react with acids, and those in Blue only react with some strong oxidizing acids.
Why is hydrogen included in the reactivity series?
Despite being a non-metal, hydrogen is often included in the reactivity series since it helps compare the reactivities of the metals. The metals placed above hydrogen in the series can displace it from acids such as HCl and H 2 SO 4 (since they are more reactive).
What metals react with water?
Reaction Between Metals and Water. Calcium and the metals that are more reactive than calcium in the reactivity series can react with cold water to form the corresponding hydroxide while liberating hydrogen gas.
What can be used to predict the reactions between metals and water?
Therefore, the reactivity series of metals can be used to predict the reactions between metals and water.
Why are metals at the top of the reactivity series powerful reducing agents?
The metals at the top of the reactivity series are powerful reducing agents since they are easily oxidized. These metals tarnish/corrode very easily. The reducing ability of the metals grows weaker while traversing down the series. The electro positivity of the elements also reduces while moving down the reactivity series of metals.
