Are you looking for an answer to the topic “Which metal is less reactive copper or iron?“? We answer all your questions at the website Ecurrencythailand.com in category: +15 Marketing Blog Post Ideas And Topics For You. You will find the answer right below.
Copper is less reactive than iron. Since, according to the atomic structure, iron has four unpaired shells in its three sub shells, while copper only has one electron. As a result, iron can react faster than copper.Iron displaces copper from its solution. Therefore, copper is less reactive than iron. Copper does not displace any metal therefore it is the least reactive.Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.

What metal is less reactive than copper?
Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.
Is copper less reactive metal?
Normally, copper is less reactive metal and can not liberate H2 gas with acids. But, when a copper piece is dipped in concentrated H2SO4, copper piece is found to disintegrate after a period of time.
Why is CU less reactive than iron?
Copper is less reactive than iron. Since, according to the atomic structure, iron has four unpaired shells in its three sub shells, while copper only has one electron. As a result, iron can react faster than copper. One general example is that iron rusts when it comes into contact with moist air, while copper does not.
Why is iron not reactive?
Explanation: Iron, chemically speaking, is quite low on the full reactivity series (see below), ranking only just above copper. From the atomic structure of iron, its reactivity is mediocre, having two possible forms of bonding in its excited electronic state.
Which is less reactive metal?
Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum.

Reactivity series – GCSE Chemistry (Single Science) Revision
A reactivity series of metals could include any elements. For example: A list of elements from most reactive to least reactive: potassium, sodium, lithium.
Which metal is less reactive: copper or iron? – Sarthaks …
Copper is less reactive than iron. For example, if we put Iron nail into copper sulphate solution. Iron nail will displace copper from …
Which metal is less reactive copper or iron – Tutorix
Copper is less reactive than iron according to the reactivity series given below. 0. Related Doubts. Which metal is more reactive: iron or …
Why is copper less reactive than zinc?
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.
Which one is more reactive than iron metal?
The metals copper, silver gold and platinum are less reactive thanhydrogen and they do not replace hydrogen from water or acid. … Zinccan displace copper from copper sulphate solution and iron from ferrous sulphate solution. So zinc is more reactive than iron and copper.
Why is copper not reactive?
On the other hand, copper is placed lower than hydrogen in the activity series of metals (which means that it is less reactive than hydrogen) and therefore does not react with HCl .
Which is most 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.
Which metal (Copper, Aluminium, Brass or Iron) is the better conductor?
Images related to the topicWhich metal (Copper, Aluminium, Brass or Iron) is the better conductor?
Why is iron less reactive than 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.
Is iron a reactive metal?
Iron is reactive but not as reactive as sodium. The table on the right shows the different metals in order of reactivity with the most reactive on top. Click on the names of the metals to see where they appear on the periodic table below.
What is the reactivity of iron?
Pure iron is quite reactive. In a very finely divided state metallic iron is pyrophoric (i.e., it ignites spontaneously).
Is iron reactive or nonreactive?
Iron, aluminum, and unlined copper are reactive metals, which mean that when some foods are cooked or left in one for an extended period of time, the metal particles in the porous vessel can chemically interfere with the ingredients, causing them to turn metallic in flavor.
Which metal is more reactive Fe or Cu and why?
Solution : Iron displaces copper from its salt solution. Hence, iron is more reactive than copper.
Is copper more reactive than carbon?
Use displacement reactions to show that lead and copper are less reactive than carbon: Mix the metal oxide and carbon powder thoroughly – use more carbon than metal oxide. Heat the mixture strongly in an old test tube (pyrex), for several minutes.
Which element is more reactive?
Alkali metals (situated far away from transitional metals and noble gases) are the most reactive elemental group. Cesium is second from the bottom of this group, with 6 electron shells, so it fits all the characteristics of a reactive atom, therefore making it the most reactive element.
Is iron less reactive than aluminium?
Aluminium is said to be more reactive than iron, towards oxygen (or air). Yet iron undergoes corrosion to a greater extent than aluminium.
What is the reactivity of copper?
Copper is low on the reactivity scale. This low reactivity, combined with its malleability makes it ideal for use in architecture. It can be cut and hammered into ornate shapes and it will protect itself with a pale green coating of copper salts called a patina.

Which is highly reactive and less reactive metal?
It is a series of metals arranged according to their reactivity in which the most reactive metal i.e. potassium is at the top of the series and the least reactive metal i.e. gold is at the bottom. The most reactive metal is Na. The less reactive metals are Zn, Fe, Pb.
Which is the most reactive and least reactive metal?
Solution : Most reactive metal : K (potassium) , Least reactive metal : Au (gold).
