To determine which of the given substances are not compounds, we need to understand the definition of a compound. A compound is a substance formed when two or more elements are chemically bonded together. Let's analyze each option: 1. **Chlorine gas (Cl₂)**: This is a diatomic molecule consisting of two chlorine atoms. Since it is made of only one element, it is **not a compound**. 2. **Potassium chloride (KCl)**: This is made up of potassium (K) and chlorine (Cl). Since it consists of two different elements, it is a **compound**. ...
