electrons - Why is zinc more reactive than copper

2019-3-17 · Zinc is more reactive than copper not because the last sub orbital of zinc is $\ce{4s^2}$ while of copper is $\ce{4s^1}$ if it is than according to this magnesium should be more reactive than sodium as the last sub orbital of magnesium is $\ce{3s^2}$ while of sodium is $\ce{3s^1}$ so this is not the case why zinc is more reactive than copper, ok remeer it.

To Study the Relative Reactivity of Metals using Salt

Zinc can displace copper from copper sulphate solution and iron from ferrous sulphate solution. So zinc is more reactive than iron and copper. If a piece of zinc metal is added to aluminium sulphate solution, no reaction takes place. So aluminium is more reactive than zinc. If small pieces of copper are added into solutions of zinc sulphate
