Understanding the Reactivity Series

What do metals have in common regarding their electron arrangement?

• They have a full outer shell of electrons.

• They have electrons in the outermost shell that they want to get rid of.

• They have no electrons in the outer shell.

• They have electrons in the innermost shell that they want to get rid of.

What is formed when metals react with acids?

• Metal oxides and water

• Metal hydroxides and hydrogen

• Salts and hydrogen gas

• Metal carbonates and carbon dioxide

Which group of metals is the most reactive?

• Group 1 metals

• Group 2 metals

• Transition metals

• Noble gases

What happens when potassium reacts with hydrochloric acid?

• It forms potassium oxide and water.

• It forms potassium chloride and hydrogen, reacting explosively.

• It forms potassium hydroxide and hydrogen.

• It forms potassium carbonate and carbon dioxide.

Which metal will not react with water?

• Lithium

• Magnesium

• Zinc

• Potassium

What is a displacement reaction?

• A reaction where a less reactive metal displaces a more reactive one.

• A reaction where a more reactive metal displaces a less reactive one.

• A reaction where metals form oxides.

• A reaction where metals form carbonates.

What happens when magnesium is placed in a solution of iron sulfate?

• Magnesium displaces iron to form magnesium sulfate and iron.

• Iron displaces magnesium to form iron sulfate and magnesium.

• No reaction occurs.

• Magnesium forms magnesium oxide.

Which of the following metals will not react with hydrochloric acid?

• Copper

• Zinc

• Iron

• Magnesium

What is the result of reacting lithium with water?

• Lithium oxide and water

• Lithium hydroxide and hydrogen

• Lithium carbonate and carbon dioxide

• Lithium chloride and hydrogen

How can we ensure a fair test when comparing the reactivity of metals?

• Use different masses of metal samples.

• Use different types of acids for each metal.

• Ensure each metal sample has the same mass and surface area, and use the same type and concentration of acid.

• Use different concentrations of acid for each metal.
