No, they are isotopes with the same Atomic Mass. But they are isotopes of different elements and so are very different from on another.
For example nitrogen-16 and nitrogen-14 are isotopes of the same element.
Yes, nitrogen monoxide is a molecular compound with a formula of NO.
In one molecule of nitrogen dioxide (NO2), there is one oxygen atom. Therefore, there is one molecule of oxygen in each molecule of nitrogen dioxide.
No, oxygen-17 and oxygen-18 are different isotopes of oxygen. They differ in the number of neutrons each atom contains. Oxygen-17 has 8 protons and 9 neutrons while oxygen-18 has 8 protons and 10 neutrons.
It is very difficult to describe the bonding in nitrous oxide using a simple valency model. It consists of two nitrogen atoms and one oxygen atom. You can say that each nitrogen atom has a double bond with the other nitrogen atom, and one of the nitrogen atoms has a double bond with the oxygen atom, but that requires putting charges on some of the atoms. You need to invoke the ideas of delocalization or resonance if you wish to describe it accurately.
No. Nitrogen dioxide is a compound of nitrogen an oxygen, meaning that the two elements are chemical bonded together to form a different chemical with its own unique set of properties. In a mixture the nitrogen and oxygen would not be bonded to each other and would retain their individual properties.
Carbon and nitrogen isotopes are not isotopes of each other. They are different elements with their own set of isotopes. Carbon isotopes include carbon-12, carbon-13, and carbon-14, while nitrogen isotopes include nitrogen-14 and nitrogen-15.
Oxygen and nitrogen will not directly chemically react with each other under normal conditions. They will typically stay as separate molecules in the air.
because the molecules of oxygen only react at high temperatures
The bonds are hydrogen bonds.

Air is mostly a mixture of gases, primarily nitrogen and oxygen. Nitrogen makes up about 78% of air, while oxygen makes up about 21%. These gases are not chemically bonded and can be separated from each other.
It sure can; basically, each element has radioactive isotopes. Check the Wikipedia article "isotopes of oxygen" for more details.

Oxygen and nitrogen are both stable, non-reactive gases and do not readily react with each other under normal conditions. However, at very high temperatures and pressures, they can react to form nitrogen oxides.

Isotopes of oxygen differ in the number of neutrons they contain in their nuclei. Oxygen has three naturally occurring isotopes: oxygen-16 (8 neutrons), oxygen-17 (9 neutrons), and oxygen-18 (10 neutrons). The differences in neutron count affect the atomic weight and stability of each isotope.
Nitrogen monoxide has the formula NO, so each molecule of NO contains 1 oxygen atom.
