Q

State what happens when a metal is extracted

A

he higher a metal is on the electrochemical series, the more difficult it is to extract it from its ore.

During extraction, metal ions are reduced to form metal atoms.

Q

Describe electrolysis

A

Electrolysis is a method of extraction that uses electricity to decompose an ionic compound into its elements. This process involves passing an electric current through an electrolyte (a substance that conducts electricity when molten or dissolved), causing chemical changes at the electrodes.
