Why is N2 not considered a true mineral?

Mohammad Perwez · Accepted Answer

Dear student,
Nitrogen is not considered a true mineral because nitrogen is one
of the constituent of atmospheric gases and plants is not able to
utilise it as nitrogen, rather plants utilises nitrogen in the form
of ammonia or nitrate Nitrate is formed in the soil by weathering
of rocks or by atmospheric nitrogen fixation Therefore nitrogen is
not a true mineral for plant nutrition
