many radicals are _____ reactive, why

### Highly reactive, because there is a tendency for the unpaired electron to form a covalent bond with an unpaired electron on another radical.

## Step1: Understanding Radicals### Radicals are atoms, molecules, or ions that have unpaired valence electrons. This unpaired electron makes them highly reactive because they seek to stabilize by pairing up with other electrons.## Step2: Reactivity of Radicals### The high reactivity of radicals is due to the tendency of the unpaired electron to form a covalent bond with an unpaired electron on another radical. This process leads to the formation of a stable molecule or ion.
