We know that reactivity series is arranged in such a way that as we move from bottom to top, reactivity of the metals increases. As we can see in the series, out of all the given options
gold
is the least reactive metal.
Which is the least reactive metal?
Platinum
is the least reactive of all the options. Aluminium, iron are also formed in combined forms in the natural surroundings.
What is the most reactive metal least reactive?
In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements. The reactivity of alkali metals increases from the top to the bottom of the group, so
lithium (Li) is the least reactive
alkali metal and francium (Fr) is the most reactive.
Which is lowest in the reactivity series?
The order of intensity of reactivity is known as reactivity series. Reactivity of element decreases on moving from top to bottom in the given reactivity series. In the reactivity series,
copper, gold, and silver
are at the bottom and hence are least reactive.
Which is the most reactive and least reactive metal in the reactivity series?
Elements, Compounds and Mixtures | Exercise
State the most reactive and the least reactive metals from the following –
Zn, Ag, Na, Fe, Cu
, Pb. Potassium is at the top of this series and gold is at the bottom. The most reactive from Zn, Ag, Na, Fe, Cu, Pb is Na.
How can you tell which metal is more reactive?
The primary difference between metals is the ease with which they undergo chemical reactions.
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.
Which metal is more reactive?
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 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.
Which alkali metal is least reactive with water?
The reactivity of alkali metals increases from the top to the bottom of the group, so
lithium (Li)
is the least reactive alkali metal and francium (Fr) is the most reactive.
What is the most reactive metal and why?
The attraction from the positive nucleus to the negative electron is less. This makes it easier to remove the electron and makes the atom more reactive. Experimentally speaking,
cesium (caesium)
is the most reactive metal.
Which is less reactive mg or Zn Why?
Exploring the Activity Series Chart
This shows
magnesium is more reactive than zinc
and both metals are more reactive than hydrogen. This third displacement reaction can be used for any metal that appears lower than itself on the table. The further apart the two metals appear, the more vigorous the reaction.
Which metal does not react with water?
Metals like
aluminium, iron and zinc
do not react either with cold or hot water. But they react with steam to form the metal oxide and hydrogen. Metals such as lead, copper, silver and gold do not react with water at all.
Is iron very reactive?
Pure iron is quite reactive
. In a very finely divided state metallic iron is pyrophoric (i.e., it ignites spontaneously).
Is magnesium less reactive metal?
Displacement order
Magnesium is more reactive than copper
, so magnesium can displace copper from a copper sulfate solution to create magnesium sulfate. Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.
Which is the highest reactive element?
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.
Which metal is most reactive and stored in kerosene?
Sodium
is stored in kerosene as it is a highly reactive metal.
