Question

Highly reactive elements occur in nature in ______ state.

Answer 1

Highly reactive elements occur in nature in combined state.

Explanation:

Highly reactive elements, such as alkali metals (like sodium and potassium) or halogens, tend to lose, gain, or share electrons to achieve a stable configuration. Because they react readily with environmental elements like oxygen, sulphur, moisture, and carbon dioxide, they are never found free in nature. Instead, they always exist as stable chemical compounds, such as oxides, halides, carbonates, or sulphides.
