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.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.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 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 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. They all have low densities, melting points and boiling points, and they tend to form solutions with a pH greater than 7.

The reactivity series.
| Element | Reaction with dilute acids |
|---|---|
| Copper | Very slowly |
| Silver | Barely reacts |
| Gold | Does not react |
Which is the correct order of reactivity series?
3) There is the order of reactivity of metals and in order to remember this order, one has to recite this order in any possible simple form. The order of reactivity of metals is as follows, Potassium > Sodium > Lithium > Calcium > Magnesium > Aluminium > Zinc > Iron > Copper > Silver > Gold.
Is Zinc highly reactive?
It is a fairly reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen.

What is metal reactivity?
The reactivity series of metals is a chart listing metals in order of decreasing reactivity. In general, the more reactive a metal is: the more vigorously it reacts with other substances. the more easily it loses electrons to form positive ions (cations)
Why is Caesium the most reactive metal?
Among the alkali metals, Cs is the most reactive because its outermost electron is more loosely bound than the outermost electron of the other alkali metals. This is due to the increase in distance between the outermost electron shell and the nucleus. Was this answer helpful?

Why is Caesium so reactive?
The higher the effective nuclear charge is, the greater the attraction is between electrons and the nucleus. Cesium’s low effective nuclear charge indicates that the nucleus does a poor job of attracting its electrons. Both of these factors make cesium extremely reactive.
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 potassium the most reactive metal?
– Potassium metal has more number of shells compared to sodium and thus it becomes easy to remove one electron from its outermost orbital ( less ionization enthalpy). – So, out of given metals, Potassium is the most reactive metal. Therefore, potassium is the most reactive metal among the given options.
Is Zn more reactive than FE?
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 aluminium a reactive metal?
Aluminium does not react very well with the oxygen in the air but it is in fact quite a reactive metal. The reason it does not react is that is has already reacted, but the aluminium oxide has formed in a thin, tightly bonded layer that protects the aluminium foil from further attack.
Is mercury highly reactive?
Properties of Mercury
Mercury is less reactive than its neighboring metals, including cadmium and zinc. One reason that mercury is more inert than other elements is because it doesn’t give up its valence electrons easily.
What is the order of reactivity of metal?
Na > Ca > Mg > Al > Zn > Fe > Sn > Pb > Cu > Ag. Was this answer helpful?

Which is the least 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.
What is the increasing order of reactivity?
The increasing order of reactivity among group 1 elements is Li < Na < K < Rb CI > Br > I.
