The phrase "a number of reactive" is correct and usable in written English.
It can be used when referring to multiple reactive elements, substances, or individuals in a specific context, such as chemistry or behavior.
Example: "In the experiment, a number of reactive compounds were combined to observe their interactions."
Alternatives: "several reactive" or "various reactive".

A number of different reactive oxygen species, including the superoxide anion (O2-.), singlet oxygen (1O2), hydroxyl radical (·OH) and the hydrogen peroxide (H2O2) are produced when plants are under heavy metal stress, but these ROS can pose a severe threat when produced in larger amounts.
