Mass # = protons + neutron
Atomic # = protons
Charge = the overall charge on the atom when the number of electrons
change
This chemical symbol represents Nitrogen-15. This means that this nitrogen
atom has 7 protons based on the atomic number. Because the mass number
is the number of protons and neutrons and we already know that it has 7
protons based on the atomic #, there are 8 neutrons. Noticing that it has a
charge of +3, the nitrogen atom has three fewer electrons to give it the +3
charge. That means that this nitrogen atom has 4 electrons.
