(c) Fe > Na > Mg > Au
(b) K > Ca > Na > Mg
(d) Cu > Fe >K> Na​

Answer 1

Answer:

I think the answer is option c

Explanation:

“The reactivity series lists metal compounds, including magnesium sulphur and lead, in their order of reactivity, with the least reactive at the top. Those at the top and bottom are most keen to react with other elements to form compounds. Less reactive metals will displace other metals from their compounds.
