Because of its high reactivity, the metal is classified as a hazardous material.

This is due to its high reactivity and instability.

The compound may also re-ignite after extinction because of its high reactivity.

However, it is only the cyclooctyne that can be easily modified for higher reactivity.

The black solid has been studied only moderately, probably because of its high reactivity.

They are known by their higher reactivities and shorter lifetimes.

An alkali earth metal, calcium is almost never found in nature due to its high reactivity with water.

Because of its high reactivity, it is never found as a pure element.

However, its use in terrestrial applications is usually limited by its high reactivity with air.

Because of its high reactivity, it is a dangerous chemical.
