In the nucleus.
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
An atom with a mass of 15 amu is most likely a nitrogen atom, as the atomic mass of nitrogen is approximately 14.01 amu. This means that the atom may have gained or lost a particle, altering its mass slightly.
Most of the mass in an atom is in the nucleus. The protons and neutrons are about the same weight, 1 amu. The elecrtons are 1/1840 of the mass of an proton. Neutrons are 2000 times heavier than electrons and protons have an equal mass of neutrons
