Here's why:
* Stability: Nitrogen atoms are very stable in their diatomic form. The triple bond between the two nitrogen atoms is very strong, making the molecule relatively unreactive.
* Abundance: This form of nitrogen makes up about 78% of the Earth's atmosphere, making it the most abundant gas in our air.
While nitrogen is an important component of many organic molecules, it's relatively inert in its diatomic form. To be used by living things, it needs to be converted into usable forms through processes like nitrogen fixation.
