bcoz oxygen is used by living beings were nitrogen is not used.
yes
There are two elements. They are Fluorine and Oxygen
Oxygen has a higher electronegativity than nitrogen does, so when sharing electrons with hydrogen, the sharing is more uneven in the case of oxygen than it is with nitrogen. Oxygen, in other words, will attract electrons more strongly than nitrogen does and therefore will wind up with a more negative charge (hydrogen, which supplies the extra electrons to the oxygen, has a correspondingly higher positive charge).
Nitrogen is lighter than oxygen
Nitrogen is an inert gas it maintains a proper ratio of oxygen requred by living organisms if oxygen is in higher ratio the respiratory organs become oxidized and more oxygen in blood is harmful as low concentration of oxygen.
nitrogen is lighter than oxygen
yes
Oxygen, the element with an atomic number higher by one than that of nitrogen.

Nitrogen is lighter than oxygen
Yes, it is true because the density of oxygen is higher than the density of nitrogen.
Nitrogen is an inert gas it maintains a proper ratio of oxygen requred by living organisms if oxygen is in higher ratio the respiratory organs become oxidized and more oxygen in blood is harmful as low concentration of oxygen.
half filled P orbitals increase the stability resulting in higher ionization energy
If Nitrogen would have properties like Fluorine(and higher reactivity than Oxygen), it could have displaced Oxygen from Water to form a compound Hydrogen Nitride
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
No, nitrogen effuse faster than oxygen.
