Question

Quizplus · Accepted Answer

The mass number of an atom is the sum of its protons and neutrons, which in the case of nitrogen is 14 (7+7). The atomic mass of an atom, on the other hand, is the weighted average of the masses of all the isotopes of that element, taking into account their abundances. The most abundant isotope of nitrogen has a mass number of 14, which means that the atomic mass of nitrogen is also approximately 14 daltons. Therefore, option E is the correct statement.
