Copper is more reactive than calcium. true or false?

Answer;

The above statement is false

Explanation;

Copper is less reactive than Calcium.

This is because Calcium is higher in the reactivity series of metals compared to copper and thus reacts more than copper.

The reactivity series of metals is vital tool that is used in determining the products of displacement reactions and the reactivity of metals in other reactions. The higher the metal is in the reactivity series, the more reactive it is and conversely the lower the metal in the reactivity series the less reactive it is.

In this case, calcium is higher in the reactivity series than copper thus more reactive.

The given statement is false.

Explanation:

Electronic configuration of calcium is , that is, there are two extra electrons. So, in order to attain stability calcium loses two electrons readily.

Whereas electronic configuration of copper is . Since, it has completely filled d-orbital so, it is stable in nature and thus, does not react readily.

Therefore, we can conclude that reactivity of calcium is more than copper. That is why, the given statement is false.
