In a nuclear reaction, the mass and atomic numbers must always remain conserved. Nuclear reactions do not obey the law of conservation of matter and mass.
The mass number are the superscript before the symbol of the nuclide
The atomic number is the subscript.
The sum of the atomic number on the left hand side equals that on the right hand side. This goes for the mass number too.
