Sure! Here’s a simple grade question based on the topic "The Nature of Chemistry":
**Question:**
Explain the difference between an element and a compound. Provide one example of each and describe how they are represented in chemical formulas.
**Answer Key:**
- An **element** is a pure substance that cannot be broken down into simpler substances by chemical means. It is made up of only one type of atom. For example, oxygen (O) is an element.
- A **compound** is a substance formed when two or more elements are chemically bonded together. Compounds can be broken down into their constituent elements through chemical reactions. For example, water (H₂O) is a compound made of two hydrogen atoms and one oxygen atom.
In chemical formulas, elements are represented by their chemical symbols (e.g., O for oxygen), and compounds are represented by a combination of these symbols along with subscripts indicating the number of each type of atom present (e.g., H₂O for water).
