As the atomic number of nitrogen is 7, the most abundant isotope of this atmospheric gas must have 7 neutrons (14.007 - 7 = about 7), and this will make nitrogen-14 that isotope that is most abundant.

How is an isotope and a mass number related?

An isotope is member of an element of Mass Number differing from the average; for example, the most common isotope of Carbon is 12C (6 protons, 6 neutrons), where 13C and 14C would be less common (even unstable, radioactive) isotopes. So isotopes are varying forms of an element, differing in mass number.
