Question

How to find the reactivity of metals?

Answer 1

for metals reactivity increases down a grp and frm left to right across a period

Answer 2

Some metals are usually are less reactive whereas some metals are highly reactive. The metals which lose electrons readily are less reactive compared to that of metals which forms positive ions. For instance consider the below equation.

In the above equation, Zinc is immersed in a copper sulfate solution; Zinc uproots copper from copper sulphate solution since it is a metal. From this, it is evident that Zinc is more reactive as copper cannot uproot Zinc from Zinc sulphate solution.
