• group 2 metals are the most reactive metals

In chemistry, a displacement reaction is where

• a more reactive metal displaces a less reactive metal from its compound

• two reactive metals join together to form an alloy

• a less reactive metal displaces a more reactive metal from its compound

• a more reactive metal is removed from its compound by a less reactive metal

Look at part of the reactivity series? Which one of the following statements is correct?
