Answer :
Answer:
free radical is the correct answer.
Explanation:
- Free radicals contain unpaired electron in the atomic orbital makes the free radical very reactive and unstable.
- Free radicals produce negative effects on human health as they cause damage to the human cells, diseases, and aging when they react with substances present in the human body
- Example of free radicals: hydroxyl radical.
Explanation:
A specie with no charge and containing one or more number of unpaired electrons is known as a free radical.
These free radicals tend to attain stable configuration by gaining an electron from another atom. Hence, they fill their outer energy levels.
For example, a free radical of chlorine will readily combine with a hydrogen atom in order to attain stability and it leads to the formation of a new chemical bond between the hydrogen and chlorine atom.
As a result, it will form a hydrogen free radical.
Thus, we can conclude that free radical is a highly reactive chemical species with one or more unpaired electrons.
