Because in air is some more N-15 isotope than in soil, rock, water. Caused by influence of cosmic radiation.
Chemical nitrogen 1 it is pure as it does not have any inert gases. 2 it is lighter compared to atmospheric nitrogen. 3 it is highly reactive. Atmospheric nitrogen 1 it has 1% inert gases. 2 it is heavier than chemical nitrogen due to the dust particles. 3 it is less reactive because of the inert gases.
it is heavier
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
This chemical element is carbon.
Almost all solid elements are heavier than air. This is why these elements do not float under normal atmospheric situations.

it is heavier
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Dry air is about 80% nitrogen. The remaining 20% consists mostly of things that are heavier than nitrogen, so dry air is very slightly heavier than nitrogen.
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
Atmospheric nitrogen fixation is the process where nitrogen is converted into ammonia. Without nitrogen, organisms couldn't grow, and organisms need nitrogen more than anything to grow.
Yes, ammonia vapor is heavier than nitrogen. The molecular weight of ammonia (NH3) is 17 grams per mole, while nitrogen (N2) has a molecular weight of 28 grams per mole. This difference in molecular weight causes ammonia vapor to be denser and heavier than nitrogen gas.
No, nitrogen dioxide is not a metal. It is a chemical compound composed of nitrogen and oxygen. Metals are elements that exhibit characteristics like high electrical conductivity, malleability, and luster, which nitrogen dioxide does not possess.
Almost all solid elements are heavier than air. This is why these elements do not float under normal atmospheric situations.
If "heavier than" in the question is interpreted to mean "has an atomic mass greater than", the answer is nitrogen
Nitrogen, has a atomic weight roughly 14 times heavier then that of hydrogen.
Fluorine is heavier than nitrogen because fluorine has more protons and neutrons in its atomic structure compared to nitrogen. The atomic mass of fluorine is approximately 19 amu, while the atomic mass of nitrogen is approximately 14 amu. Additionally, fluorine is located in a higher period (row) on the periodic table compared to nitrogen, which contributes to its heavier weight.
