Question

define reactivity series with example​

Answer 1

Deacreasing order of reactivity series = K,Na

Answer 2

Explanation:

The reactivity series lists metal compounds, including magnesium sulphur and lead, in their order of reactivity, with the least reactive at the top. ... Less reactive metals will displace other metals from their compounds. For example, magnesium will displace iron from iron oxide to form iron and magnesium carbonate.
