Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.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.Copper is less reactive than hydrogen then why does it displace hydrogen in the reaction of sulphuric acid but not in the reaction of HCL? In displacement reaction, more reactive metal displaces less reactive metal.

Which is less reactive zinc or copper?
Therefore, zinc is more reactive than copper. Aluminium has the ability to displace zinc, iron, copper from their respective salt solutions and therefore is more reactive than them.
Which is more reactive metal or copper?
Hence, iron is more reactive than copper.

Is aluminium more reactive than copper?
Answers to student questions. Aluminium appears less reactive than 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 metal is less reactive copper or zinc Brainly?
Copper is less reactive than zinc.
Why is copper less reactive than hydrogen?
Since, this radox couple have positive standard electrode potential, they are a weak reducing agent and therefore, Cu is less reactive than Hydrogen. Hence, Cu is less reactive than Hydrogen as is positive.
Why is more reactive than copper?
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.

| Copper | Very slowly |
| Silver | Barely reacts |
| Gold | Does not react |
What is the least reactive element?
The least reactive elements are the noble gases. Within this group, helium is the least reactive element, forming no stable compounds. Metal can have multiple oxidation states and tend to have intermediate reactivity. Metals with low reactivity are called noble metals.
Which is more reactive copper or zinc?
The metallic bond of copper is therefore stronger than zinc, so more energy is required to break this bond in order for it to react. Since more energy is required for copper to react, we can say that zinc is more reactive than copper.
Why Zinc is more reactive than copper?
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 copper more reactive than hydrogen?
>>Cu is less reactive than hydrogen.
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 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.
Is copper more reactive than lead?
Lead is more reactive than copper and less reactive than tin.
Which metals are more reactive?
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.
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.

Is zinc less reactive than iron?
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.
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.
