State what is meant by the ‘reactivity series of metals’
Advertisements
उत्तर
Activity series of metals:
“Is a series of arrangements of metals in decreasing order of their reactivity.”
i.e. metals at the top are most reactive and least reactive metals are at the bottom of the series. The metal above is more reactive than the lower metal. In other words, K is more reactive than all the metals below it and Na is more reactive than all the metals below it.
