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.Therefore, for practical purposes, Cesium is often regarded as the most reactive metal. Cesium is one of the few elemental metals that is liquid at room temperature, but also reacts explosively with water.Reactivity of Metals Chart
Metals at the top of the chart, such as potassium, sodium, and lithium, are highly reactive and can burst into flame or explode when they come in contact with water.

What are reactive metals?
Reactive metal is a group of metal elements that can form a reaction with acids, water, mineral acids and powerful oxidizing acids. This group can be identified with the activity or reactivity series, which determines the most reactive metals from highest to lowest.
Is gold a reactive metal?
Gold is one of the noblest—that is, least chemically reactive—of the transition elements. It is not attacked by oxygen or sulfur, although it will react readily with halogens or with solutions containing or generating chlorine, such as aqua regia.
What are the 10 least reactive metals?
The least reactive metals would be Platinum, Gold, Palladium, Osmium, Silver, Rhodium, Iridium and Ruthenium, Copper, and Lead in the decreasing order. The basic structure of society is built with the matter around us.
Is iron more reactive than copper?
Conclusion. In such a reaction, the more reactive metal displaces the less reactive metal. Thus, the above activity shows that iron is more reactive than copper.
Is iron more reactive than nickel?
Looking at the reactivity series, we see that nickel is below iron, but above lead.

Is gold the least reactive metal?
Found free in nature, oxides decompose with heating. Silver, gold, and platinum are metals with the least reactivity.
Is platinum more reactive than gold?
Platinum is placed below gold in the reactivity series.
What is the most reactive metal group?
Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
Why is caesium the most 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.
Is caesium more reactive than francium?
The electrons become a little closer to the nucleus than expected and they also become slightly harder to remove than expected. Thus Caesium is more reactive than Francium.
Is platinum reactive yes or no?
Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal.
What are the 2 most reactive groups on the periodic table?
The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons.
What the most 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.
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.
Is Caesium a metal?
Caesium is a soft, gold-coloured metal that is quickly attacked by air and reacts explosively in water. The most common use for caesium compounds is as a drilling fluid.

What order are metals in?
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.
Is zinc more 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.
