Question

Why is magnesium more reactive than zinc why is magnesium more reactive than zinc...​

Answer 1

Answer:

The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom. For example, both magnesium and zinc can react with hydrogen ions to displace H2 from a solution by the reactions:

Mg(s) + 2 H+(aq) → H2(g) + Mg2+(aq)

Zn(s) + 2 H+(aq) → H2(g) + Zn2+(aq)

Both metals react with the hydrogen ions, but magnesium metal can also displace zinc ions in solution by the reaction:

Mg(s) + Zn2+ → Zn(s) + Mg2+

This shows magnesium is more reactive than zinc and both metals are more reactive than hydrogen. This third displacement reaction can be used for any metal that appears lower than itself on the table. The further apart the two metals appear, the more vigorous the reaction. Adding a metal like copper to zinc ions will not displace the zinc since copper appears lower than zinc on the table.

Answer 2

Answer:

More reactive metals more readily lose these electrons, so when for example it reacts with oxygen - giving that characteristic white flame - it is violently giving up its electrons to oxygen. since zn and al are situated at the right of magnesium thus magnesium is more reactive than zinc and aluminium.
