**Step-by-Step Solution:** 1. **Understanding Native State**: The term "native state" refers to the condition in which certain metals exist in nature in their pure metallic form, without being combined with other elements or forming compounds. 2. **Identifying Characteristics**: Metals that can be found in the native state are typically chemically inert or have very low reactivity. This means they do not easily react with other elements, such as oxygen or carbon dioxide. 3. **Examples of Native Metals**: - **Gold (Au)**: Gold is a well-known metal that is highly resistant to corrosion and oxidation, allowing it to exist in its pure form in nature. ...
