🔍 Explanation:

- Chemical symbols are standardized abbreviations for elements (e.g., "O" for oxygen).
- Some symbols come from Latin names (e.g., *Fe* from *Ferrum* for iron, *Na* from *Natrium* for sodium).
- Memorizing common elements and their symbols is essential in chemistry.
- This worksheet helps reinforce recognition between names and symbols — a foundational skill in science.
