Explanation:

- Part 1: Each element has a unique symbol, often derived from its name in English or another language (e.g., "Au" for gold comes from the Latin word "aurum").
- Part 2: Matching symbols to their names requires familiarity with the periodic table. For example, "Cu" is the symbol for copper because it comes from the Latin word "cuprum."

This exercise reinforces understanding of the periodic table and helps memorize common elements and their symbols.
