Question

Which metal is less reactive: copper or iron?

Answer 1

Answer:

copper is less reactive than iron

Explanation:

As you can see copper does not replace iron from its solution since it is less reactive than iron .

A more reactive metal displaces a less reactive metal from its solution

Answer 2

Answer: Copper metal is less reactive than iron.

Explanation:

Iron has 2 electrons in its outermost orbit and copper has 4 electrons in its outermost orbit. During bonding metals lose electrons easily since iron has only 2 electrons it loses its electrons easily when compared to copper which has 4 electrons.

Though both have equal no of shells copper is less reactive than iron.
