∙ 13y agoThe common reactivity series of metals in decreasing order of reactivity is:
K, Na, Ba, Ca, Mg , Al, Mn, Zn, Fe, Ni, Sn, Pb, H, Cu,Hg, Ag, Au,Pt.
H is present to differentiate the highly reactive and very less reactive metals.

How does the activity series of metals reflect the stability of metals?
We arrange metals into an ordered list with the best reducing agent at the top and the worst reducing agent at the bottom. This is an Activity Series for metals. Metals near the top of the list give up electrons most easily. Those metals near the bottom of the list give up electrons with difficulty. Hydrogen, even though it is not a metal, can be placed in the list. Metals above hydrogen in the Activity Series will react with 1.0 Molar hydrochloric acid at room temperature. The Activity Series for metals is developed by experiment.A list of metals arranged in order of reactivity~APEX
What is meant by reactivty series of metals?
Reactivity series is a list of metals arranged in the order of their decreasing activities.
Are all metals reactive?
Aluminium oxide (dialuminium trioxide, Al2O3) is not considered a toxic substance.
Why does sodium and potassium reacts when placed in water?
There is something known as the activity series of metals. It is a list of the metals in order based on reactivity. For example, calcium is more reactive that magnesium, therefore calcium is higher on the list. Basically, when it comes to single replacement reactions, if you have a calcium ion or atom in the presence of a compound with magnesium in it, the calcium will replace the magnesium in the compound. Now, this is relevant because the 5 most reactive metals, lithium, potassium, strontium, calcium and sodium, are so reactive that they actually displace the hydrogen in water, making hydrogen gas and a hydroxide (with the metal). Potassium + Water = Potassium Hydroxide + Hydrogen gas. These 5 elements are so reactive because of their low ionization energies. They want to lose electrons and become part of a compound; even more so that a hydrogen atom does. So they will replace the hydrogen atom because it requires less energy to do so.
How does activity series of metals reflect the stability of metals?
The metals highest on the list are the least stable.
What metal is alkali metal?
This is the first column in the Periodic Table. There are six metals that are "Alkali Metals" and six that are "Alkali Earth Metals". The Alkali metals are:LithiumSodiumPotassiumRubidiumCaesiumFranciumThese metals get more reactive as you go down the list...Hope I helped :D
What are reactive metals?
It's basically an indication of what metals are capable of displacing others. There's a list called the "reactivity series", and any metal on the list will displace anything lower on the list and be displaced by anything higher on the list.
Which metals is more reactive copper or sodium?
I think sodium is more reactive than copper, because on the Reactivity Series list sodium is higher than copper.

Which are the least reactive metals and why?
Ia group (Group 1) the alkali metals are the most reactive and they can lose an electron easily.The least reactive metals are:-The so-called platinum metals, ruthenium, rhodium, palladium, osmium, iridium, and platinum which are transition metals in groups 8,9,10.Althoough i consider osmium is a bit too reactive to be included.The coinage metals copper, silver, gold are quite unreactive particluarly gold.Mercury.Some metals appear to be very unreactive because their surfaces are passivated by an oxide layer e.g. aluminium and titanium.
What is activity series?
The Activity Series of metals is a very essential part in predicting the result of many reactions. The Activity series is a chart which list's metals in order of declining reactivity. The metals on the top of the series are the most reactive and the ones in the bottom are the least reactive. The first five elements on the chart are highly reactive metals; which will react with water and steam. It is essential to know, that reactions should be performed in room temperature for the activity series to work well. Many would predict that metals with low ionization energy and lower electro negativity would me more active, because they are more vulnerable to lose electrons in a reaction. However, while these properties do affect an elements place in the series, there are other factors that affect an elements activity
What does the activity series of metals give?
The activity series of metals lists the metals in order of reactivity, with the most reactive metals listed at the top, and the least reactive metals listed at the bottom. When determining the results of a single replacement (displacement) reaction, you compare the two metals according to their location on the list. If the elemental metal is higher on the list, it will replace the other metal in the compound. For example, Al + 3AgNO3 --> 3Ag + Al(NO3)3 occurs because the metal aluminum, Al, is higher than silver, Ag, on the metal reactivity list, and replaces the silver in the silver nitrate, AgNO3, to form elemental silver, Ag, and the compound aluminum nitrate, Al(NO3)3. The reverse reaction, 3Ag + Al(NO3)3 --> Al + 3Ag(NO3)3 will not occur, because the silver is lower on the list than aluminum, and cannot replace the aluminum in the aluminum nitrate, so the correct equation is Ag + Al(NO3)3 --> n.r. (which means "no reaction").

What is the correct list of elemental families in order going from left to right?
Alkali metals, transition metals, halogens or Transition metals, halogens, noble gases or Alkali earth metals, halogens, noble gases
What is more reactive than sodium?
Very high. It's an alkali metal, in the most reactive metal family. Don't get me wrong, it's the weakest of the alkali metals, but more reactive than any other metals. For a VERY violent reaction, try potassium. For a VERY dangerous reaction, use pure francium.
