Reactive metals occur in native state.

Explanation

To determine whether the statement "Reactive metals occur in native state" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- The term "native state" refers to metals that are found in their pure, uncombined form in nature.
- "Reactive metals" are those that readily react with other elements or compounds, such as oxygen or sulfur.

2. **Refer to the Reactivity Series**:
- The reactivity series ranks metals based on their reactivity. The most reactive metals, such as potassium and sodium, are at the top, while less reactive metals, like gold and platinum, are at the bottom.

3. **Identify Reactive Metals**:
- Metals that are above hydrogen in the reactivity series (e.g., potassium, sodium, calcium) are considered reactive. They tend to form compounds with other elements rather than existing in their native state.

4. **Examine the Statement**:
- The statement claims that reactive metals occur in their native state. However, since reactive metals readily react with other elements, they do not typically exist in their pure form.

5. **Conclusion**:
- Therefore, the statement "Reactive metals occur in native state" is **false**. Reactive metals are usually found in the form of compounds (like oxides or sulfides) rather than in their native state.

### Final Answer:
The statement "Reactive metals occur in native state" is **false**.
