Quick Q&A Before You Revise

Why are metals usually found as ores?

Because many metals are reactive and combine with other substances in nature instead of remaining free.

Can a non-metal be shiny?

Yes. Iodine is a non-metal but it is lustrous.

Why is graphite special?

Graphite is special because it is a non-metal that conducts electricity.

What is the easiest way to use the reactivity series?

Check whether the metal is above or below hydrogen, or above or below the metal in the salt solution.

Why is zinc coating protective?

Zinc blocks contact with air and moisture and also corrodes before iron, giving extra protection.

Do all metals react with acids?

No. Metals below hydrogen, such as copper and silver, do not react with dilute acids to liberate hydrogen.

Why is iron extraction asked so often?

It brings together ore, reduction, slag formation, and industrial application in one standard process.

What should I revise last from this chapter?

Revise the property exceptions, the reactivity series, ionic compound properties, and the named corrosion-prevention methods.
