Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the fundamental process?Electrochemical technique utilizing direct electric current to drive endergonic chemical reactions
2. What is the industrial production?Primary method for producing reactive metals (Al, Mg, Na) and high-purity copper
3. How does electrolysis break things apart?It works by sending electricity through a liquid or melted salt, which moves charged particles (ions) to the electrodes. At the electrodes, the ions gain or lose electrons, breaking apart the material.
4. Why is electrolysis important for making metals?It lets us produce metals like aluminum, magnesium, and sodium that are too reactive to get from rocks by normal chemistry.

Direct Electric Current (DC): Electrical current flowing consistently in one direction, essential for electrolysis.
Electrolyte: A substance containing free ions that conducts electricity when molten or dissolved.
Decomposition Potential: The minimum voltage required to initiate electrolysis in a specific system.
Anode and Cathode: The electrodes where oxidation (anode) and reduction (cathode) occur, respectively.
