What is the order of reactivity of metals?
“The reactivity series lists metal compounds, including magnesium sulphur and lead, in their order of reactivity, with the least reactive at the top. Those at the top and bottom are most keen to react with other elements to form compounds. Less reactive metals will displace other metals from their compounds.
Which metal show has highest reactivity?
What is the easiest way to remember the reactivity series of metals?
A good way to remember the order of a reactivity series of metals is to use the first letter of each one to make up a silly sentence. For example: People Say Little Children Make A Zebra Ill Constantly Sniffing Giraffes.
What is the order of decreasing reactivity of the metals?
In order of decreasing reactivity, the metals potassium, sodium, lithium, calcium, magnesium, zinc, iron and copper can be put in order of their reactivity from their reactions with water and dilute acids.
What metal is the least reactive?
Silver, gold, and platinum are metals with the least reactivity. They are found in nature.
What is the second most reactive metal?
alkaline earth metals
What makes a metal reactive?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. ... Alkali metals are highly reactive because they readily lose the single electron in their outermost shell.
What is a very reactive metal?
The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium.
Is sodium highly 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.

What is the most reactive metal and why?
Reactivity 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.
Why is FR so reactive?
Explain why Francium is the most reactive Group 1 element in terms of its electronic structure. All group 1 elements have 1 electron in their outer shell, making this the electron that is involved in reactions. ... This means that the outer electron is more easily removed in Francium than other group 1 elements.
Is Zn more reactive than CU?
Answer: We find, Zinc is placed higher than Copper in the Electro-chemical Series, since Zinc is more reactive than Copper. Now, the reason is that Zinc loses its valence electrons more easily than Copper to take part in a reaction.
Is Iron less reactive than Aluminium?
Because aluminium is more reactive than iron, it displaces iron from iron(III) oxide. The aluminium removes oxygen from the iron(III) oxide: iron is reduced.
What elements have the highest reactivity?
Reactivity Trend in the Periodic Table
- The most reactive element is fluorine, the first element in the halogen group.
- The most reactive metal is francium, the last alkali metal (and most expensive element). ...
- The least reactive elements are the noble gases.
Why is magnesium more reactive than copper?
Due to the relative reactivity of metals, given in the reactivity series, when combined they compete to form ionic compounds with other chemicals. More reactive metals will displace (push out) less reactive metals from metal salt compounds. ... The magnesium displaces the copper as it is a more reactive metal.
Is copper less reactive than oxygen?
Copper has a lower reactivity with oxygen than lead. Copper(II) oxide is formed.
How do you know if a metal is more reactive than hydrogen?
Whether hydrogen or a metal is produced at the cathode depends on the position of the metal in the metal reactivity series : the metal is produced at the cathode if it is less reactive than hydrogen. hydrogen is produced at the cathode if the metal is more reactive than hydrogen.
Why is Fe2+ more reactive than Fe3+?
Fe3+ is more reactive since it has a higher valency state. ... In a reductive environment, Fe3+ will be more reactive. Fe3 is more stable than Fe2, so Fe2 is more reactive than Fe3.
Is Silver reactive?
Silver is not very reactive. It will not react with air or water. It will tarnish, however, when coming into contact with sulfur compounds.
Why is silver not reactive?
The simplest answer I can give is that silver (e.g) is a good conductor of electricity because of its sea of delocalised electrons between the layers of metal ions. However it is not highly reactive because you would need a lot of energy to break the metallic bonds within each of those layers.
Why is sodium reactive?
Sodium on the opposite side of the table has the opposite properties. Its single outer electron makes the metal highly reactive and ready to combine with others at the first opportunity – such as the moment the metal hits water.
Is Silver flammable?
Silver is not flammable.

It also is mined from the minerals acanthite (silver sulfide) and stephanite. Silver also is found in the common minerals chlorargyrite (silver chloride) and polybasite. Silver is mined in many countries, but most comes from the USA, Canada, Mexico, Peru and Bolivia.
