The atomic number of nitrogen is 7, and the atomic mass is 14.01. What can we deduce from this?
Answer (2)
The number of protons in the nucleus of an Nitrogen atom is 7. And the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes. In the case of nitrogen the atomic mass is 14.01
The atomic number of nitrogen (7) indicates it has 7 protons and 7 electrons. Its atomic mass (14.01) is a weighted average of its isotopes, primarily 14N and 15N. This means the most common nitrogen isotope has 7 neutrons, but variations exist due to other isotopes.
