which of the following quantities are conserved during radioactive decay?

in a nuclear decay two major properties are conserved the charges and  atomic mass.  for example , in the following nuclear decay ¹₀n+¹⁰₅B→⁷₃Li+⁴₂He.

 Te atomic number and are the subscript,  the atomic number on the right hand side must be equal to the atomic number on the left hand side, the mass is the mass number of the respective atoms, they are the superscript, the mass number on the right hand side must be equal to the right hand side on the left hand side.
