Nitrogen has an atomic mass of 14.007 amu. Nitrogen has two common isotopes. Oneof the isotopes has a mass of 14.003 amu and a relative abundance of 99.632%. What is the mass of the other isotope?

13 protons and 14 neutrons.  this also means that the amount of electrons also is 13 because electrons have the same amount as protons..the atomic number means the amount of protons (which effectively tells you the electrons) the atomic mass, tells you the amount of protons and neutrons in the nucleus.hope this .
