The reactivity series has various important applications, the different reactions and their feasibility can be easily predicted by these metals. However the reactivities of the different metals towards the oxygen atom vary.Ĭharacteristics of the reactivity series of metals:ġ.The metals at the top of the reactivity series are most reactive and they are powerful reducing agents.Ģ.The reducing ability of the metals decreases down the series since the reactivity of the metals decreases down the series.ģ.The electropositive character also decreases down the series.Ĥ.Elements found above the hydrogen in the activity series can liberate Hydrogen during the reaction while the elements below the hydrogen in the reactivity series cannot do so.ĥ.Metals that are placed higher on the reactivity series can displace the metals placed in the lower portion of the reactivity series however the vice versa is not possible. (b) The reaction of metals with acids: K and Na react with HCl and. Reactivity of metals decreases on moving from top to bottom in the given series. Metals like Cu, Hg, Ag, Pt do not react with steam or water, hence they are least reactive. dilute hydrochloric acid (except for alkali metals). When metals are placed in order of their reactivity it is. We apologise for the inconvenience, but hope that the new images will provide you with an even better learning experience. The reactivity of a metal is determined by how easily it can lose electrons to form positive ions. The metal oxides are formed when they react with the atmospheric oxygen. The order of intensity of reactivity of metals is known as reactivity series of metals. Disclaimer: Due to unforeseen difficulties, we have had to take down the images on this notes page.

The series given above clearly shows that the metals form the cations readily by losing the electrons.
