Mirror nuclei is where the number of protons of element one (Z1) equal the number of neutrons of element two (N2), the number of protons of element two (Z2) equal the number of neutrons in element one (N1) and the mass number is the same.
In short, Z1=N2 and Z2=N1.
Formula showing how the masses must be the same.
Z1 = Atomic number of first element Z2 = Atomic number of second element A1 = Atomic mass of first element A2 = Atomic mass of second element N1 = Number of neutrons in first element N2 = Number of neutrons in second element Z1 = A1 - N1 = N2 Z2 = A2 - N2 = N1 N1 = A1 - N2 A2 - N2 = A1 - N2 A2 = A1
Examples of mirror nuclei:
H with mass number 3 and He with mass number 3.
