Answer:
Protons and electrons can be determined by atomic number:
no. of p+ = no. of e- = atomic number
Neutrons can be determined by atomic mass (when atomic no. is known)
Atomic no. + no. of neutrons= atomic mass
no. of protons + no. of neutrons = atomic mass
Thus
no. of neutrons = atomic mass - no. of protons
Hope this helps!!!
