-3 as it has 3 more electrons than protons giving it a negative charge :)
No
Explanation:
Neither copper nor iron will be able to replace zinc ions in solution. This is because both copper and iron are lower than zinc in the activity series.
- The activity series depicts the reactivity of metals.
- Metals higher up in the series are more reactive than the lower ones.
- A metal high above another will displace the one below in solution.
- This is the driving force for a single displacement reaction.
- The position of an element determines its reactivity.
- Copper and iron are lower than zinc and are less reactive.
