Does chromium have high reactivity?
Chemical properties Chromium is a fairly active metal. It does not react with water, but reacts with most acids. It combines with oxygen at room temperature to form chromium oxide (Cr 2 O 3 ). Chromium oxide forms a thin layer on the surface of the metal, protecting it from further corrosion (rusting).
Which of the metal is highest in reactivity series?
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.
What is an example of activity series?
An activity series is a list of substances ranked in order of relative reactivity. so zinc is also more active than hydrogen. so magnesium is more active than zinc. The activity series including these elements would be Mg > Zn > H.
Which is more reactive chromium?
1. C Chromium can displace iron from its salt solution. Hence, chromium is more reactive than iron (eliminate option D).
Is chromium browser a virus?
While Chromium is a legitimate browser, its open-source code has made it unstable, full of bugs and a target for spreading viruses.
Is chromium a rare earth metal?
What is “rare metal”? chromium, which are found in abundance in the earth’s crust, are also considered to be rare metals. This is because manganese and chromium have been essential elements for the industrial world since its early days, used as additives to enhance the properties of iron.
Which metal can easily cut with knife?
Sodium
Sodium is silver white color metal with malleable and ductile property. It is the metal that can easily be cut with a knife.
Where is iodine on the activity series?
The activity series of the halogens is fluorine > chlorine > bromine > iodine.
How do you calculate activity series?
The reactivity series is a series of metals, in order of reactivity from highest to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series….P3: Activity Series of Metals.
| Metals | Metal Ion | Reactivity |
|---|---|---|
| Pt | Pt+ | highly unreactive |
Which is more active iron or copper?
Copper does not have a higher reactivity than iron. Since copper is less reactive than iron, it does not displace iron from its solution.
Where is cesium on the activity series?
Cesium is second from the bottom of this group, has 6 shells of electrons, and it matches the features of a reactive atom, making it the most reactive element.
