The most chemically reactive metals are the alkali metals. Francium is the most reactive of these and of all metal (although it is present on earth only in exceedingly small q â¦ uantities, due to its radioactivity). The most reactive element available in useful quantities in Flourine.
Reactive oxygen species (ROS) are chemically reactive molecules containing oxygen. Examples include peroxides. superoxide, hydroxyl radical, and singlet oxygen. In a biological context, ROS are formed as a natural byproduct of the normal metabolism of oxygen and have important roles in cell signaling and homeostasis.
