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.
Assuming you are talking about oxygen gas and nitrogen gas the answer is yes. Each and every gas is affected by temperature.
Nitrogen is composed of molecules each containing two nitrogen atoms
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.
Both nitrogen and oxygen are nonmetal elements that commonly occur as diatomic gasses. That is, they form molecules consisting of two atoms each. Both are also highly electronegative.
oxygen, hydrogen and oxygen. More accurately it is made up of 70% nitrogen, 21% oxygen, around 1% hydrogen, and the other 8% is made up of noble gases that appear in the periodic table around 1% each
No! Nuclides with different element names are never isotopes of each other, because their nuclei contain different numbers of protons and therefore are not chemically alike.
because the molecules of oxygen only react at high temperatures
The bonds are hydrogen bonds.

It sure can; basically, each element has radioactive isotopes. Check the Wikipedia article "isotopes of oxygen" for more details.
eight electrons
Ozone
Nitrogen monoxide has the formula NO, so each molecule of NO contains 1 oxygen atom.
hydrogen bonds!
Dinitrogen Pentoxide is made up of nitrogen and oxygen. The percentage of composition of each of these elements is: 25.936% nitrogen and 74.064% oxygen.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
Nitrogen ~ 78% Oxygen ~ 21% CO2(and other gasses) ~ 1%
