Ex-Most reactive- Potassium

Least reactive- Gold

Answer 2

Reaction with water and acids. ...Metals in the middle of the reactivity series, such as iron, will react with acids such as sulfuric acid (but not water at normal temperatures) to givehydrogen and a metal salt, such as iron(II) sulfate: Fe (s) + H2SO4 (l) → FeSO4 (aq) + H2 (g)
